i am the lemon zester of destruction

It was actually at Christmas when I was first introduced to Mystery Science Theater 3000, by my rad cousin Ron.  He stumbled across a marathon while channel surfing and, as I recall, had the rest of us glued to the wood-paneled RCA and laughing like loons for hours.  So it seems appropriate that Hulu choose Christmas to gift us with episodes of MST3K.  Thank you, Hulu!

My favourite is still the MST3K take on This Island Earth, which was also their theatrical release, although The Pumaman definitely ranks up there, too.  What's your MST fave?
