Matt and Nancy and I made this lamp using a dozen harmonicas. The lamp actually worked. Next to the lamp was a Monica collage with a red button in the middle of her mouth. PRESS HERE, it said, and when you pressed it you heard Nancy sing a new version of the Chipmonks' harmonica song:

I sure like girls, all kinds of girls
From Jennifer to Monica
I teach them all to suck and blow
When they play my harmonica!

People pushed the button all night long.
