As for funny.. the "Cat Killer" is #1, followed closely by "Parachuting" and "Kissing Monkey Butt". The "Clydesdale Zoo" and "Dancing Burt" are also keepers.
My husband and I also liked the ad where M.C. Hammer got thrown over the fence (Frito-Lay?) and the other AmeriQuest commercial... the one with the guy in the convenience store ("You're being robbed"). The "Cat Killer" one was fantastic!
