What was the most random guest appearance on a TV show?

Burt Reynolds showing up in the final minutes of "The Golden Girls" episode they spent talking about him. He was a huge star at the time and he just pops in for a minute like nothing.

Ed Sheeran in Game of Thrones.

“Im Sinbad, and this is Rob Thomas from Matchbox Twenty!”

Prince on New Girl. EDIT: Should have read the body text: he apparently loved the show.

Robin Williams and Billy Crystal on Friends.

That time when Larry David appeared on Hannah Montana and Curb Your Enthusiasm was mentioned on a Disney teen sitcom. Which looking at it today, it was surreal.

Werner Hertzog on Parks and Rec

Nixon on Laugh In.

I mean… they had a while bunch of famous guitar players show up on the Drew Carey show (like Joe Walsh and Dave Mustaine) to “audition“ for Drew's band. It was funny though.

Marshawn Lynch on Brooklyn 99.

Iggy Pop playing a Vorta in season 6 or 7 of Star Trek: Deep Space Nine. What's the god father of punk doing ransoming Quarks mother for a POW?

Jack Black and Lizzo in The Mandalorian. I guess at least Lizzo made an effort to act but Jack Black just felt like Jack Black and completely took me out of the scene.

Joe Piscopo being the only comedian from the 90s that the holodeck can produce on Star Trek the Next Generation to teach Data about jokes

Elon Musk on Rick and Morty still feels like a fever dream. They turned him into “Elon Tusk” and the whole thing just came off like a weird flex instead of an actual joke. It didn’t really match the show’s usual tone and you could kinda feel the awkwardness through the screen.

Paris Hilton in Veronica Mars

Ed Norton in the first season on Modern Family when he was a pretty big star really surprised me at the time. Apparently he was/is friends with Ty Burrell.

bob uecker was himself on an episode of teen titans go

Boy George on ***The A-Team***

Also Stewie from Family Guy on Bones.

Warren Buffett in The Office

All the 80s icons that appeared on Pete and Pete

Colonel Klink doing a crossover in the Batman series. Just so many questions. Shouldn't Nazi's operating in Gotham City be a bigger concern to Batman than whatever the hell the Riddler was on about that week? Batman seemed a little less surprised than he was about it, almost helpful in a way to whatever he was up to. How does the timeline work? Is some kind of crossed timeline part of the plot? Come to think of it, where the hell were the superheroes during wwii anyway? It illudes to WWII still being underway during the 60s batman timeline. Just....sooo many questions... https://www.youtube.com/watch?v=UHD_53UqBeA

Billy Crystal and Robin Williams in Friends. It had no context, and the scene literally only existed for the main characters to go “what was that all about”? Love them both and not saying it was or wasn’t funny but it really felt like the director went “just go up there and do your thing, maybe do a funny accent and improv a scene or something”.

“I just know there are some great f****** trains here in Bangor!”

Stephen King on Sons of Anarchy

Betty White in Bones

Conan O'Brien plays a non-speaking background bar patron in an episode of How I Met Your Mother.

It’s Always Sunny has had some pretty random ones: Tiger Woods, Don Cheadle, P Diddy, Jason Sudeikis, Guillermo del Toro, etc…

Jimmy Fallon in Band of Brothers

There was a bottle episode of E.R., with Ewan McGregor. It was a great change for the series, but it did follow a different format and had a different intensity (at least to me).

Taylor Swift in New Girl

Wayne Brady shows up as a Jaffa badguy in Stargate, and it's weird.

Britney Spears on How I Met Your Mother

Jesse "The Body" Ventura and Alex Trebek showing up as Men In Black on the X-Files was totally, unexpectedly glorious.

Bob Dylan on Pawn Stars

Steven Tyler on Lizzie McGuire was a strange one.

Bruce Willis on Friends never felt right. Still don't.

Penn and Teller on the West Wing

The Doobie Brothers guesting on What's Happening!! in 1978.

Charles Barkley on Clerks the Animates Series. *Jay*: Hi Im Jay *Silent Bob*: and Im Silent Bob *Charles Barkley*: and Im Charles Barkley ... *Jay*: What the hell are you doing here!? **Charles walks off sad**

Jack Black & Owen Wilson on Community was a good one

Iggy Pop in Star Trek: Deep Space Nine. Also the king of Jordan in Star Trek the Next Generation.

For me, it was Billie Joe Armstrong popping up on Nurse Jackie.

Liam Neeson on Atlanta

Tricky D*** on ***Laugh-In*** (1968). Sammy Davis, Jr on ***All In The Family*** (1972), and pretty much any of the window cameos when the dynamic duo was climbing a building on ***Batman*** (1966).

If you're going for random, I didn't expect to see Daffy Duck on The Drew Carey Show

Remember when Monk met Korn?

Mark Hamill on Man Down

Kevin Bacon on Mad About You. They find out Jamie is pregnant, but are worried about telling the family, because some of them will get mad if they weren’t told before someone else. They decide to have a dinner party on Friday, invite the whole family, and tell everybody at once. However, did a desire to just tell somebody is burning Jamie up inside so she tells a random woman on the elevator. Paul goes a little crazy and explains to her the 7° of separation thing, I think he makes reference to the 7° of Kevin Bacon version. Jamie dismisses it. Hijynx ensue throughout the week. The dinner party happens. People are upset at certain people found out before they did. They all go to leave the apartment to go to the restaurant and as they open the door, the woman walks by with her date, Kevin Bacon, who turns to Jamie and says, “Oh, I heard you’re pregnant. Congratulations.”

Penn & Teller on Babylon 5.

Bea Arthur, Art Carney & Jefferson Starship on the Star Wars Holiday Special.

Bradley Cooper on Abbott Elementary. It was the week before the Oscar’s so I guess it was a last min push.

George Clooney on South Park

Puff Diddy. Always sunny.

Mark Lin-Baker from Perfect Strangers playing himself on The Leftovers. The episode he was in, they changed the opening theme to a version of the Perfect Strangers theme song. I was so confused, until I found out why. I loved it.

Marie Osmond was the first celebrity that Pamela Anderson's crew saved from kidnappers on VIP.

Worf on the final episode of *Webster*, which was not the series finale. Bonus points for it being a clip show. https://memory-alpha.fandom.com/wiki/Webster

That was basically every sitcom in the 70s and 80s. They once even had Robin Williams cameo as himself on Mork & Mindy. And it wasn't limited to sitcoms. Famous people were always showing up as themselves on CHiPs.

Mama Cass Elliott in The New Scooby Doo Movies episode “The Haunted Candy Factory.”

The Young Ones. The gang go down to the local pub for a pint and shenanigans and the live band that night is... Motorhead playing "The Ace of Spades"

[deleted]

Steven A Smith as Brick (no last name) on General Hospital. Recurring character, apparently

Shaq on SouthLAnd. Caught me off guard. He just pulls up as a fellow LAPD cop and starts chatting with one of the guys.

Richard Nixon on Laugh-In

Gary Busey in scrubs.

Mr Blobby in Keeping Up Appearances?

Alf popped up in an episode of Mr. Robot and OMG it was so cool. One of my favorite parts of that story is they got their Emmy noms for season one the same week they were taping that episode. So they have a puppeteer laying on the floor of an old car filming an 80s style sitcom episode the same time they found out that they were being considered for this big honor. Rami Malek won the Emmy for Outstanding Lead Actor in a Drama Series that year.

So, what's the craziest guest star on *The Simpsons*?

We should separate fictional characters from celebrity appearances. Tom Selleck on Friends is very different from Nancy Reagan on Diff'rent Strokes.

The cast of dropout's gamechanger showing up on the Rookie. I had heard Sam showed up but the fact that it was part of the story of the episode was kinda weird

Aside from Globetrotters on Scooby Do?

Wayne Brady in SG1 comes to mind. It was so random.

Johnny Depp with the 'Suits you' guys on The fast show. Or Paul Rudd in the finale of UK/Irish show Moone boy

Jesse Ventura and Alex Trebek play men in black in an episode of the X-Files

Violent Femmes on Sabrina the Teenage Witch. The fact that everyone's swooning over Gordon Gano is probably the most unbelievable thing in this show which includes the use of magic as an everyday occurrence.

Johnny Carson had a visit from Santa. Under that makeup and costume was Jack Palance...

Robocop on WCW Nitro.

Guillermo del Toro as Pappy Mcpoyle in IASIP
