There was a big fight at www.zombiekeeper.com over a similar image-someone too the box for "American Psycho" and put Bush holding the knife, with a reflection of a terrified Iraqi woman holding her child in the blade of the knife.
Mer personally it doesn't matter. Eeryone can make fun of whoever but it dosen't change the world we live in. These are funny though- I like the Mortal Kombat one. 😛
Oh, and if anyone hasn't seen it, go to www.albinoblacksheep.com and download the flash file "Bomb Saddam." THIS stuff is funny.
