Michael J. Nelson

Michael John Nelson

{DAYSSINCEBIRTH(birth=1964-10-11)}{DAYSSINCEBIRTH}

As head writer for all ten Mystery Science Theater 3000 seasons in which it wasn't a mostly-improvised local show, host/performer for nearly half the episodes, and head honcho at RiffTrax, I think it's safe to say Mike Nelson is the world's preeminent movie riffer.
