Harry Pothead
Hari Pothead is an unfortunate orphan who grew up to be a dope addict with some pretty serious delusions about being a wizard and all. His addiction left him with a serious head injury and an ugly scar on the forehead.

When he is not high, he is sweeping the streets, and when no one is looking, he likes to get nasty with the broomstick. He tried to be a snake-charmer when he realised his charm never worked on the ladies. Unfortunately the only snake that did not bite him (Nagini), left him for his sworn enemy after she explained that she was NOT a woman in disguise.
dude...you gotta slow down with the grass...you don't want to end up getting sorcerer stoned like Harry Pothead
