David Bowie (Will Ferrell) visits Bing Crosby (John C. Reilly) during the holidays to sing a mash-up duet of two Christmas classics, "Peace on Earth" & "The Little Drummer Boy." If you remember the original (also below the jump), their get-to-know-you conversation is pretty uncomfortable, hilarious and awkward. Crosby's line of questioning basically amounts to, "do you alien freaks do normal x-mas stuff besides anal rape and self-mutilation?" and Ferrell and Reilly do a good job of underscoring that vibe without underlining it too obviously. Both clips below.
