I appreciate that we live in the timeline where the Supernatural/Scooby-Doo crossover is the undisputed gold standard for crossovers.

The Scooby-Doo and Supernatural crossover was frickin gold!

Who’s ready for the next Scooby doo crossover with Courage the Cowardly dog!!!!🕸🦇👻

[mr.decencykeepinitreal]

"Supernatural" & "Scooby-Doo."
"Archer" & "Bob's Burgers."

Impressive top 2 though.
👏👏👏👏

Phineas and ferb mission marvel was one of the best first crossover ever in Disney channel history especially seeing the creator himself Stan Lee.

The last episode of "Newhart" revealed that the entire series had been a dream of Bob Newhart's character from "The Bob Newhart Show."
Most people would be furious to have the rug pulled out from under them like that, but Bob Newhart is so lovable, he gets a pass.

Almost every Scooby Doo crossover is so unexpected that it’s actually unexpected when it’s not unexpected and expected when it’s unexpected. You follow?

Seeing Freddy bang his head against a tree realizing that they’ve been chasing real estate developers instead of the real deals it’s really hilarious.

I LOVE that X-Files/COPS crossover, it's one of my favorite hours of TV ever. The best part is when Scully is doing an autopsy and the morgue worker asks why she went along with the COPS cameras. Scully, bent over a body, looks dead at the camera, puts on the biggest and fakest smile in history, and says "Because the FBI has nothing to hide." Perfection.

Anyone here remember the crossover specials on the lilo and stitch series? They had the main cast of recess appear, the proud family, Kim possible and American dragon Jake long

I just want everybody to know, that the Supernatural/Scooby-Doo crossover episode is the best Supernatural episode of all time!

CW's Crisis on Infinite Earth's and the DCEU. I remember walking in on my brother watching it and was surprised that the CW's Barry Allen and the DCEU's Barry Allen were having a conversation. I really thought THAT would show up on the list, and was half expecting the Scooby Doo-Johny Bravo and Batman crossovers to appear.

Holy hell. That cops episode scared the hell out of me as a kid.

For Thea White (aka Muriel). It’ll be the last time hearing her reprise the role in the Scooby-Doo/Courage crossover before she passed recently.

Brooklyn Nine-Nine & New Girl was definitely my favorite crossover! I loved watching Jake Peralta and Jess Day on screen together.

Oh, the episode with a surprise guest, the original Freddy Kruger actor himself, Robert Englund.
😃

I feel like the Johnny Bravo / Scooby Doo crossover should have gotten an honorable mention.

[mlggamer]

I think I remember seeing the crossover with fresh prince and the Jeffersons weirdly enough
