What poster @Dick-Withers is not telling you is that last year he actually won an ugly sweater contest at our neighbors house (and received as his prize a lottery ticket for eight dollars that is still sitting on his dresser in our bedroom). He may not remember because he was exceptionally drunk at the time.
The sweater is one I found in a thrift store, featuring a Hawaiian print motif of the nativity with "and the word was made flesh and dwelt among us" printed all over it in French. It is truly the ugliest and most bizarre article of clothing ever.
FWIW I borrowed a sweater from my mother for this event that said HO HO HO across the chest. I came in second place. My mom thinks I won second in a Christmas fashion show bc I thought it would be rude to tell her the true intent of borrowing it.
