Shirt Design: NURSE JOKER

Do you want one? I know I do!
I just couldn't resist the idea of Nurse!Joker on a t-shirt! And I kind of made the stuff in the syringe look like Zydrate...
O.O The Joker in the world of Repo! the Genetic Opera... Now there's a cool idea!
Anywho, I plan to do a whole bunch of t-shirt designs. Some characters on my list include:
-Batman
-Nightcrawler
-Wolverine
-Spiderman
-Gambit
-Hulk

Yeah, but feel free to suggest some more.
