Either these guys are terrible at drawing, or...
When a group of men are given a drunken friend passed out on their couch and a permanent marker, genuine scientific studies have shown that 99.7% of them will draw some male genitalia on their face. However, it turns out that when asked to draw the female anatomy, most guys are not so skilled.
We're not about to sit here and say that we could do any better, but we will say in our own defence that we're terrible at drawing and would consider ourselves abstract expressionists.
If you ask us, the rather strange variations on the female anatomy that emerge from this piece are as a result of the fact that a lot more time was spent drawing phallic objects on people's walls on Bebo. It's the internet's fault. In fairness, at least their art can been commended as being strongly vaginal.
