I've been a fan of Irregular Webcomic for ages. He does great Lego spoofs of: Indiana Jones, Star Wars, Harry Potter, Shakespeare, the Nigerian Finance Minister spam scam, and the Croc Hunter, as well as an ongoing series of D&D miniature adventures.

At one point, Steve was hired as the new Care of Magical Creatures teacher while Hagrid was away, and summoned (and wrestled) Cthulu.
