This is easily my favorite film of a man touching himself on the Internet.

Ari Fararooy, a videographer and world traveler, recently went on a backpacking tour of South America. Fortunately, he brought his camera and his skills at creating ingenious short films based on his travels (he previously made shorts about his trip to Joshua Tree and one entitled Driving Across America By Myself) to create this epic ball-tapping chase across the continent. This puts your average "dancing in various places" imitators to shame, so much so that I'm actually kind of worried about his balls.
