A man wants a Christmas gift for his wife. Something different.
He wanders into a pet shop, and talks to the proprietor
who says, "I've got just the thing. This parrot is named Chet,
and he's perfect for Christmas. Watch this."The shopkeeper
pulls out a cigarette lighter, holds it under the bird's right wing,
lights it, and the bird sings, "Jingle Bells." Then
he holds it under the bird's left wing,
lights it, and the bird sings, "Silent Night!"

The man asks to try out the bird, and the proprietor
says, "OK, just don't hold the lighter too close;
you don't want to burn his wings."

The man does the left wing and the bird sings "Silent Night".
He does the right wing and the bird sings "Jingle Bells".

They haggle and reach a good price, with the shopkeeper throwing in the lighter.
The man takes the bird home. He decides to make sure Chet will sing
here at the house, and he does it again: left wing, "Silent Night";
right wing, "Jingle Bells".

On a lark he places the lighter between the birds legs.
He flicks it on and Chet sings: "Chet's nuts roasting on an open fire ..."
