Dear Vice - Challenge accepted
Remember that letter we got a while back from a girl who wanted to partake of our wacky "experiments"? We told her fine, you want in, then go to a bar where people don't recognize your likeness and see how many guys you can get to show you their nuts. We even gave her an incentive: £5 per sack, and prove it with Polaroids. If you are over 18 and still think vaginas are grosser than balls, you might want to take a look at this.
I've got a nice selection of pictures for you. It was a lot easier than I expected after a shot of whiskey (or two). Most guys didn't even think twice about it, though a few took some convincing. After taking his picture, one "model" said to me as we left the men's room that he felt like he'd just been date-raped. It was interesting but definitely not challenging.
