The X-Files-

(might be my favorite scifi series ever)
Star Trek- (original and Next Generation)
Dr. Who- (w/Tom Baker, and I vaguely remember a fat Dr. As a kid I had nightmares from the time tunnel in the opening credits, freaky!)
Red Dwarf-

(the episode were Rimmer goes nuts w/ Mr Fribbles the stuffed penguin, is one of the funniest things I've ever seen)
Highlander- (movie and series, theme music by Queen

)
Airplane 2-

(William Shatner's funniest role ever, as the Moon base commander)
