My MSNBC.com Test Pattern this week is about misheard Christmas lyrics. And there are a LOT more than I thought...
Joy to the world! The Lord has gum!
Mark, the herald angel, sings!
Frosty, the snowman! Was a jolly S.O.B.!
Jeff's nuts roasting on an open fire! (Ow, sorry to any "Jeffs" out there...)
Check the comments on that post if you want a good laugh or ten. Readers really came through with some great ones.
On a related note: I love Defective Yeti's list of Christmas carol errata, especially the last one, because DAMN SNOW.
