I Was a Teenage Zombie is the 19871 cult comedy horror favorite from director John Elias Michalakis, writer of Splatter University. The plot centers around six friends attempting to obtain some reefer to loosen up their prom dates. It's been a very dry year, so only dealer Moose (who one critic perfectly described as a meshing of Jerry Stiller with Cheech Marin) has the only marijuana in town. His product is subpar to say the least, so the buddies decide to get a refund, which Moose refuses to honor. This leads to the guys killing Moose, and disposing of his body in a contaminated river. Well, the contamination brings Moose back from the dead, as a crazed revenge seeking zombie. After Moose kills baseball stud Dan (a remarkable performance by Michael Rubin), his friends decide to dump his body into the river, thus re-animating him to serve as undead protection from the zombie Moose.
