i quote most malk players here...
"WE DO NOT!!!! NEED ANOTHER FISHMALK!"
if you want to play a joker that is fine, but a parody character to run around with is better suited to being ravanos, malkavians are meant to be played with their illness, for a better example, go to an insane assylum and tell me if they are funny, although malks may not be that messed up but they are not meant to be jokes.
here is a malk info site
