It turns out a lot of people, especially men, have a fascination with drawing penises. No one knows quite why, but I’d hazard a guess they were harboring feelings they’re frightened to explore fully.

Regardless of the reasons, this guy has turned the drawing of phallic objects into an art form.

His wife challenged him to draw penises on his new whiteboard every day for a whole year. And he passed the challenge with flying colors.

This video isn’t for those who don’t like seeing drawings of penises, because there are, obviously, rather a lot of them. 365, in fact. Some of the creations are downright scary, but it’s still a fascinating compilation.
