First of all, even if there was no muppet reference, I would make you guys see this anyway...It has to be The BEST PLAY EVER! It's the most hilarious thing I've ever seen... The muppet reference went like this: In the second act, they were doing Hamlet, in the play within a play scene...one of them brought out a puppet theater and the guy put his two hands in.. They were male and female sock puppets. Anyways the male hand sang: Mahna Mahna and the female: do DOO do doodoo and then a second time and then they started making out...it was great! It's probably not at your local blockbuster so check your local indepent-type film stores...or just locally owned ones...it's called The Complete Works of Shakespere Abridged, and it's by The Reduced Shakespere Company. GREAT STUFF!
