A man walks into a pet shop He'd like to buy a pet for his lonely, widowed mother. The shop owner shows him all of the usual stuff, hamsters, puppies, kittens, etc. and the man tells the owner that he's looking for something unique. The owner takes him to the back of the shop and introduces him to raggedy looking parrot named Chet. The man, rightfully so, is unimpressed with the parrot until the shop owner tells him that the bird sings Christmas carols. The owner explains that all the man has to do is hold a flame under the bird's right wing and he'll sing ""Silent Night"" or under the left wing and he'll sing ""O' Holy Night"". The owner proceeds with a demonstration and the man, very impressed, takes the bird home. When the man gets home he has to show his family what he has brought home so he gathers them all around the bird. He holds a candle under the bird's right wing and the bird sings a beautiful rendition of ""Silent Night"". Then the man holds the candle under the bird's left wing and the bird sings ""O' Holy Night"". The man's son asks his father what happens if you hold the candle under the bird's tail, and not knowing what might happen the man moves the candle under the bird's tail. The bird gets a concerned look on his face and starts singing ""Chet's nuts roasting on an open fire...""
