In "Grift of the Magi", Bart and Lisa sang the song in its original form.
Joy to the world the teacher's dead!
We barbecued her head!
What happened to her body?
We flushed it down the potty
And 'round and 'round it goes
And 'round and 'round it goes...
Kids, This is the holiest night of the year.
Tomorrow is Father's Day. And that makes tonight Father's Day Eve.
♪ Joy to the world, a father's born. ♪
♪ Let me receive great gifts. ♪
