In the Stupid Pet Tricks corner office, David Letterman and his beard take Sarah on a trip down memory lane, reminiscing on the SPT early days and nearly torpedoing the show's budget in the process. Back in the Writers Room, Sarah navigates the pitfalls of assuming all goats love eating cans and learns that even animals have a safeword. On stage, Sarah meets a parrot that wants way more than a cracker, a dog that could and should be in the Olympics, a cuddly bunch of speedy cockroaches, and a lazy cat who knows how to work smarter not harder. But which one will be named Stupidest Pet Trick of the Week?
