Did some portraits of Aaron from BatintheSun recently and he makes the perfect Joker, don't you think!? So I had to turn him into it for fun :]
Below is a raw image straight out of camera so you can see everything that was done to it to get him to look like the above image!

This was all shot with 2 strobes, just one main one and one for the hair!
Original image was shot with a cooler temperature, so you are actually seeing the real shot from the camera. It's something I actually do quite often (mess with the temp in cam)!
