some favorites that i’ve seen from this link:
http://www.hristu.net/ (a dancing “something” with a gangster song)
http://eelslap.com/ (eel slap, with goo for special effect)
http://cat-bounce.com/ (because who doesn’t like to see cats dropping on their heads)
you just don’t know what you are going to get, so be careful. hypnotoad almost got me in his clutches… happy clicking!
