As we were there anyway we went to see the Muppet's Movie anyway. I wasn't looking forward to it (I recently had to sit through the Smurf's Movie and I wasn't sure my parenting endurance was capable of going through that again) but I was pleasantly surprised.
In fact, I loved it. It had a real Flight of the Conchords (one of my favourite shows) feel about it. Hardly surprising since it turns out Bret McKenzie wrote some of the music.
Anyway, here's one of my favourite songs from the movie, sung by Bret and Kermit.
