I just watched this film by Frank Zappa called Baby Snakes.. And its a bit ridiculous considering he directed it.. and most of the time its either these really awesome animations by this guy bruce bickford, or its just footage of himself performing.. or making some little speech.. or just shots of the camera fixated on him while someone else is talking.
so if you can get past the first few minutes of bruce talking some hippy talk, while the camera just stares at frank zappas reaction, then you'll get to see some guys face turn into a hamburger.
