My family has our own personal version of the second verse of "Angels We Have Heard on High". It begins with "Shepherd's Wife" rather than "Shepherds, why?" and is of course the result of a child mis-hearing things.
Oh, yeah, and we all really like "Grandma Got Run Over by a Reindeer", because our grandmother is the Christmas party-pooper. She doesn't like our family's decision not to "do" Santa Claus, and she's a killjoy anyway.
I suppose if someone played "The Holly and the Ivy" at me 34 times a day I'd get a tad weary of it...
