Performance tips: Alright, so there are technically three people singing this song. But if you split up the parts into male and female vocals, it becomes a duet. It's okay to break a few rules with this song, only because it's so fun. Also, everyone in the audience is waiting for the "TIIIIIIN ROOF....RUSTED" part, so make sure you don't screw it up.
Harmonies: None. The two women harmonize with each other throughout the song, but because you are doing this as a duet, you don't have to worry about that.
Difficulty level: Hard
Should you do it if you're drunk?: Yes.
Bring down the house: Play the air guitar during the guitar solo.
