I loved Heavy Metal, Spawn and all of Bashki's work...
I grew up watching the old Popeye (especially the roto-scope episodes), Warner Brothers and Tom & Jerry. One of my teachers in college was Ken Muse, who was one of the artists and animators on the old Tommy and Jerry toons.
Later Animations that I definately enjoyed were "Aahhh Real Monsters", "The Angry Beavers" and "Rosco's Modern Life" all which were on Nickelodeon and have disappeared from the air.
I do watch a lot of amine, but I can't really pick out any in particular.
