If you get a laugh out of REALLY bad photoshopping, it's worth a look.

lol, I was reading some of the comments on the pictures, they are funny as shit.

You just gotta wonder - how the hell do these pictures make it past the editors? People without legs? Dis proportioned bodies and extra fingers? Fricken hilarious!

Even one of the splash screens in GTA4 (when you are waiting for the game to load) was on this site once - it's a graphical picture, but it still features a chick with 6 fingers on one hand.
