I love that Chevy bee-mobile from The Simpsons! Classic! Great Adam West additions, they are always funny.
The Scooby-Doo/ Johnny Bravo was great. Did you ever see the crossover the show Supernatural did with Scooby-Doo, that was funny!
Laurel and Hardy actually look funny with Michael Jackson, fits surprisingly well. I'm not sure how someone though that one up!
