Stupid Pet Tricks

David Letterman passes Sarah Silverman the Stupid Pet Tricks torch and shares with her a very special Top Ten List. Also, Sarah meets the SPT staff and smooths out some unexpected intra-office issues. On stage, Sarah welcomes a former rodeo clown and his shockingly agile best friend, a goat who can walk on two legs, a party animal that really knows how to get down, and a dog that's up there with the smartest animals in the world. But only one will take home the title of Stupidest Pet Trick of the Week!

Sarah tries to take the high road as Jack McBrayer drops in on the SPT Writers Room to brag about his new famous piece of clothing. Also, Sarah welcomes a world record-seeking dog, an overexcited horse, and a juggling duck.
