Supergirl/Wonder Girl 3: Batman never has this problem with the Joker, since he's never funny.

Previous episodes: one and two.

Even though generally DC heroes are supposed to be stoic and all-business in battle, I can't remember the Joker (or the Riddler, the Prankster, or any other allegedly funny villain) ever busting out a line that might conceivably get a chuckle out of the hero. Bizarros, though...that, and I think I'd have a hard time staying mad at Bizarro, and his earnest stupidity. Although, some artists draw him less Silver-age blocky and more zombie-like, which does lessen the charm.

And even though Kara doesn't do a terrible job of Supergirl, I would wager she has received more lectures from Superman, than anyone else has ever, from anyone, in the history of anything.
