Help find a song heard on rawdog xm?

The song is hilarious. It is acoustic... the chorus is "the mountain" and I think it's performed by two guys....they sound a lot like the Sklar brothers, but I'm sure it's not them. At one point in the song, one of the guys refers to his as "the Frodo Baggins". That's about all I can tell ya....what's the song and who's the performer(s) ?
