Any Christmas song at all done by Elvis.
I just bought an Elvis Christmas CD (only $5.00 at K-Mart).
My wife hates this CD's rendition of "Blue Christmas."
I love watching her cringe. (I'm a little sadistic.)
I've been known to leap over couches ala Superman just to turn off the radio "Blue Christmas" by Elvis comes on. I'll listen to just about ANYTHING other than that...
Oh, and Bruce Springsteen's groan-and-moan version of "Santa Claus is Coming to Town."
There's not enough eggnog on the planet to make me suffer with those two.
