A sketch from the Muppet Show. The announcer would open with: "And now... PIGS IN SPACE! Starring the indominable Link Hogthrob, the flappable first mate Miss Piggy, and the inexplicable Dr. Strangepork." I think it was an attempt by Jim Henson to spoof shows like Star Trek which were sometimes like soap operas. PIIIIIIGS IN SPAAAAAACE!
