They may look traditional, but don't be fooled. The Cherrytree Singers are more likely to sing about gettin' slizzered than about a one-horse open sleigh. The comical carolers took on Far East Movement and LMFAO -- and the results will have you, appropriately enough, L-ing your FAO.

Backed by little more than beat boxing and their own fingers snapping, the Cherrytree Singers blast through Far East Movement's 'Like a G6.' The girls sing the hook, made famous by Dev, while the guys handle the deep bass and verses. The result is somewhat operatic, rather dramatic and pretty hilarious. Towards the end of the song, even the singers can't keep a straight face.

Their cover of LMFAO's 'Sexy and I Know It' features three different vocalists, but has the same bass gentleman handling the beat. The M.O. is the same: A cappella, operatic and dramatic. Try not to giggle when the gent in the top hat belts, "I got passion in my pants and I ain't afraid to show it," then again later when he says, pretty insistently, "I work out."

The Cherrytree Singers have always had a unique spin on their spread of holiday cheer, but these clips take it to another level.
