We got the first season of the Muppet Show on DVD and watched the first two episodes. Beanie was infatuated with this dancing, caveman sort of puppet who sings manamana in the first episode and rings a bell in the second episode.
(sorry bsafe users, the filter won't let you watch this.....I had to turn mine off to get the clip!)
If you watch the clip you'll get why the following is hilarious. So it is bedtime and I think she's asleep and she looks up at me, opens her eyes and says "Manamana" in her best gravelly Muppet voice. It was hilarious.
