Comedian and roast master Jeff Ross brings the heat with a high-speed animal roast. Plus, Sarah meets a dog in some luggage, a high-jumping fox, a puzzle-solving feline, and a parrot with a knack for the pole.

David Letterman takes Sarah on an expensive stroll down memory lane. Then, back on stage, Sarah welcomes a brilliant roller-skating parrot, an acrobatic dog, a cat who can drive a car, and a bunch of racing roaches.
