The adventures of the crew of the Swinetrek was one of my favorite recurring sketches on The Muppet Show. A younger version of myself, steeped in Muppets and Star Trek, would sometimes consider what it would be like if the crew of the Enterprise ever met these silly intrepid porcine explorers. The closest I ever came to realizing those childhood imaginings is this cover from the crew of Crazy magazine.
Now, I know Miss Piggy is scary, but I would not expect this much emotion from Spock.
