When Scotty sings something other than country music, it often sounds like a parody to me (because his delivery seems affected compared to his normal speaking voice). When he first began singing this, the image that popped into my mind was Cletus from The Simpsons singing the song as part of a Simpsons Christmas special.

Lauren performed at the same show, but didn't have an exaggerated country accent (her performance starts at about 3:15 mark):
