Twelve Days of Christmas is a popular Christmas carol. The Simpsons sing their own version of it as a couch gag in "Pranks and Greens". The parody lyrics were written by Jeff Westbrook.
- The family: On the twelfth day of Christmas,
- My true love gave to me...
- Twelve Grampas grumbling,
- Eleven Barneys belching, (Barneys belch in unison)
- Ten Lennies leaping,
- Nine Carls dancing,
- Eight Moes a-milking,
- Seven Selmas smoking,
- Six Flanders praying,
- Professor Frinks: Five golden Frinks,
- The family: Four crawling nerds,
- Three-eyed fish,
- Two special Ralphs,
- And a Maggie in a Snugly.
