Do you remember those Russian guys, who played Fallout in the real life? Now they play S.T.A.L.K.E.R. - Shadow of Chernobyl. I like this game too, but I have played it only on PC :) And these people just made it real. Take a look. It's amazing. The weapons are airsoft guns.
OUCH! Bloody nipples is the most embarrassing injury ever assessed. Women are lucky, they won't get such kind of injury because of the sport bras. To achieve this njury, you’ll have to run a extended amount of time, sweating profusely, and chafe the s*%# out of your nipples on your shirt, thus the constant friction destroys your little nips and creates blood. Such an injury can only be awarded to the very few runners, that honestly, just don’t know when to stop.
There is a bunch of weird stuff, you can find in online shops. This testicle shampoo can be bought in a German online shop and it costs 5 Euro. Nice :)
