Batman Character Jokes. What do you have on these characters?

So I was talking with someone I work with the other day, and I made jokes on the Batman characters. Specifically, how he seems to bully mentally ill people. When you think about it....

Joker - Crazed Psychopath/Sociopath (Insane)
Harley Quinn - Stockholm Syndrome
Two Face - Bipolar

But I cannot seem to find anything funny to mention about others like Poison Ivy, Penguin, and Mr Freeze among other characters. Plus more.

I am asking you all to come up with lighthearted jokes about these characters I can add to this project I am working on.
