17th Century English poet Alexander Pope once famously said, "To err is human...", or in this case, it's Muppet.

A video posted on YouTube back in 2009 is making its way around the web again these days. It's outtakes from Jim Henson's Christmas classic, Emmet Otter's Jug-Band Christmas. In the scene, Ma Otter and her son Emmet appear to be standing outside a music store having a conversation when a bass drum rolls out the door into the street. Apparently the goal was for the drum to land a certain way, a goal that took repeated attempts to get right.

When I rent a DVD, I always look to see if there's a blooper reel in the special features section. Seeing actors and actresses letting loose and having some fun going off script or goofing up a scene accidentally and bursting into genuine laughter is hilarious to me. It shows them as real people who mess up like the rest of us from time to time.

What impresses me most about this video isn't so much the ad-libs the voice actors throw out there when things don't go as planned, but how the puppeteers keep the puppets in character, moving them around like real people would move when things fall apart.

By the way, if Ma Otter's voice sounds familiar it's because the character is voiced by Frank Oz. The man who has provided the voices for Yoda from Star Wars, Miss Piggy, Fozzy Bear, along with Bert and Grover from Sesame Street.
