Someone you know acting particularily dumb today? Get them a crisp, new dunce cap. You can even buy one for yourself if you want to prove your dunce-worthiness. As I'm an equal opportunity duncer, this cap comes for both genders.

These caps are derivable and use opacity maps, so you can easily make a pink, glowing, semi-transparent dunce cap. I don't know why you would want to, but you can.

Dunce Cap!
