This week's sing-off is brought to you by my Christmas Tree. Each year I make a new tree topper featuring entertainers and gay icons. Past winners have been Liza and Kathy Griffin, but this year I stepped things up and glam-rocked my tree.
And what goes better with a rockstar tree than the oddest mash-up in television and Christmas history?
David Bowie and Bing Crosby's version of "The Little Drummer Boy/Peace on Earth," is so strange and awkward that there are some great parodies of the original out there.
My personal favorite of the covers are Will Ferrell and John C. Reiley. I think they have it down better than any of the others.
Willie Nelson and Stephen Colbert are a close second. It may not be a direct cover, but it makes me laugh my ass off.
Let me know who you think did it best. Who made you laugh the hardest? Did I miss someone that deserves a chance? Post a link in the comments.
