A feature length film made for $2,000, available for free here. I've only watched chapters 1,2,and 11--and judging from the trailer some parts of it are American Pie-inspired (read: stupid)--but it's a pretty astoundingly impressive effort, especially given the budget.

Not safe for work because of "profanity, immaturity, strong displays of sexuality and politically incorrect stereotypes."

Trailer here.
