I still find "A Confederacy of Dunces" funny. Is that old time?
It seems that old cartoons are "in-bounds", so I would also like to throw Foghorn Leghorn out there. I showed it to my daughter a while back, and she asked me, "Who's the good guy?" I thought, "Oh my God, the child is right! This is like a Neil Labute play!" Everyone in the whole fucking thing is miserable...from the dog to the chickenhawk to Foghorn himself.
I never cease to laugh when Foghorn sees the pointdexter chicken putting together a Rube-Goldberg contraption for hurling a pumpkin, tells the chicken he's doing it wrong, and fixes the contraption for him. Shortly thereafter, Foghorn gets a look of confusion on his face. He turns back to ask the chicken why he's hurling a pumpkin, but before Foghorn can get the question out (as we all know, he stammers), a pumpkin slams him in the face. OBJECTIVELY FUNNY!
