Anything Looney Tunes cracks me up.

I love Daffy Ducks Fantastic Island and the famous Bugs Bunny one where he sings, "abracadabra-hocus pocus"..I believe that was with Yosemite Sam as well.

Also the other one with Bugs Bunny and Yosemite Sam...when Bugs Bunny deducts money from Sam everytime he swears..and Bugs makes him do that on purpose.

Of course, watching it stoned just tickles my funny bone even more.
