What could possibly inspire more awkward laughter than a video of David Bowie and Bing Crosby performing a "Little Drummer Boy/Peace on Earth" medley? How about a slew of today's funniest commedians spoofing the classic 1977 duet between these two clashing superstars.

This year, not one but two comedic duos have teamed up to re-create the joyous, yet awkward Christmas duet. In another one of their hilarious Funny or Die productions, Will Ferrel and John C. Reilly (David Bowie and Bing Crosby, respectively) show off their singing voices in a surprisingly faithful remake -- compelete with wigs, fake accents, and all the intergenerational weirdness of the original. To top it off, Ferrel even throws the David Bowie temper tantrum that might have been.

For a more modern, rock 'n' roll take on the Bowie-Crosby classic, Jack Black and Jason Segel appear in cartoon form to spoof the cult classic Christmas duet. In the viral clip, Black and Segel appear as themselves -- only in cartoon form. Not only do Black and Segel rock out in glorious Christmas fashion, but they're donating the proceeds from the single, which is available on iTunes, to Blue Star Families (a non-profit dedicated to helping military families).
