Ok I don't know if these are fake or not. Ever time I come across these photos I always get the impression that they are actually Jeff Probst, so I'm going with it.
Anythony Kiedis from the Red Hot Chili Peppers. Not the greatest photo, but i've never seen his cock other then when they used to wear the cock-socks back in the day.
I don't remember the reason why they did this, but apparently they were protesting something and this was there concert. I guess they made up for it by offering a free concert another night.
