James Watson, 31, fell asleep on his couch in Virginia on Saturday after he spent the night drinking heavily. He woke up at 5:30 a.m. on Saturday and saw that he had a penis drawn on his cheek in permanent marker.
He believed his roommate drew it, and so promptly ran to his room and started punching him as he slept.
Watson kept beating him until a third roommate was able to pull them apart. Unfortunately, he wasn't quick enough, as the second roommate sustained serious injuries to his face. His eye was swollen shut and bleeding as he was taken to Virginia Hospital Center.
An hour and a half later, the roommate called police and said he wanted to press charges.
They both admitted that they commonly pulled pranks on one another, but it had never escalated to violence.
In Watson's mugshot, the outline of the penis can still be seen, though it appears he tried to wash it off.
