This episode had lots of surprise twist, funny gags, and a great plot. So many things happend in this episode, when you first see it, it's so hard to predict, because it is very original. Many surprise twists were the alien crash in roswell and that Fry was his own grandfather. At first, I didn't really understand how, but afterwards it's so funny. It's so funny how Leela, Fry, and the Proffesore can't act like the 1950's properally, and are doing really weird stuff. But most of all, my favourite would be when Zoidburg got caught, and everyone was trying to learn alot about his, and the best part of that was when Zoidburg at the buffet. He thought he had to pay, but when he learned it was free, he ate up as much as he could, which made me laugh so hard.
In the end, Futurama made a funny, orginial episode, and isn't that what really counts after all?
