Leave it to this hilarious duo to revamp an old Christmas classic that — to be honest — was pretty weird to begin with. Watch David Bowie and Bing Crosby's holiday duet get even weirder in this tribute/homage/parody/whatever it is by the two dudes who brought you Talladega Nights and Stepbrothers.

For reference, we've included the original above. The Ferrell/Reilly homage is pretty spot-on, don't you think?
