What's the worst thing a performer has had to perform in the name of advertising?

Wow. What a poor, sexy, unfortunate, sexy woman.

Not advertising per se, but the celebrity cameo in this is worth a look-see.

At first, I thought they did a really good job of finding a Meatloaf lookalike, then as realization set in… NOOOOOOOOOOOOOOOO!
