I see a shitload of galleries everyday. Once in a while I come across one that just makes me stop and ask myself "Just what in the fuck were they thinking when they took those pics". Here is one such gallery.

Got any terrible galleries? Post them here. I think this one is hard to beat though. I saw an amputee gallery the other day but I can't seem to find that URL again.
