Inspired by Pigs In Space. Pigs in Space is a recurring sketch from The Muppet Show, featuring the exploits of Captain Link Hogthrob, First Mate Piggy, and Dr. Julius Strangepork leading a crew of pigs aboard the Swinetrek. The sketch, in concept, is essentially a parody of Star Trek, Lost in Space and other space operas of the 1960s and 70s.
