Because of time constraints, I still have not yet seen all 198 episodes of Mystery Science Theater 3000. I started watching when we finally got SciFi Channel in the early 2000's, a few years after it ended and didn't see even a quarter of them before SciFi replaced it with something else. But MST3K became a must watch with Prince of Space, the first episode I randomly came across one weekend, and Manos ensured I would never forget it. Last year my brother even named his cats Gypsy and Crow. This shirt makes me smile. Get yours by the end of the day or it'll be gone forever. Just $10 plus $2.75 shipping.
If you've never seen MST3K, why not start with the first three episodes that I bought? Available from fye.
