Not that I don't love Heath Ledger from The Dark Knight, but sometimes a girl wants a classic comic-style Joker, am I right?
(Bat in the Sun has made some amazing stuff and this guy totally nails the Joker. If you love Batman and/or the Clown Prince of Crime you should look them up. Images from Batman: City of Scars, Patient J, and Joker's Christmas Spectacular. Sadly, though, the only piece this group has done that I could get in high res was the one with different facial prosthetics. I have no idea why he changed, but yeah. If the nose and chin look completely different after the first forty icons? It's because they are. Side note: white makeup + harsh lighting = a huge pain.)
