Falling on your crotch is funny, when it's in a video game. So is dying multiple times over for no apparent reason.
Achievement Hunter hosts a separate YouTube channel, called Game Fails, that they fill with random deaths, glitches, and outright outrageous instances in all sorts of games. It can sometimes be hit or miss. But that's why I love when they do roundups of the best of the year, or, say, the best of April 2013.
You can watch their compilation above, but be wary of the number 1 fail of last month, cause it's a little NSFW.
