An a capella group called the "Inappropriates" doing:
A disco version of Iron Man (or maybe R&B)
A love ballad version of Prison Sex
A lounge version of Baby's Got Back
And maybe a thrash metal (a capella, mind you) cover of a sappy 80's love song like THIS ONE!
I also need a list of stupid acts, like handcuffing yourself to someone and then jumping in a lake. Or telling your wife that yes, her ass looks fat. Feel free to jump in on this one, livejournal audience.
