Gag award for doing homework in cl...?

In my high school choir, at the end of the year we have a HUGE banquet, where people get prizes, awards and stuff like that. A really big part of the night is the "gag award" portion. It is supposed to be really funny as people get stupid little gifts for things they have done in choir (its good lighthearted fun). An example would be, "the biggest pest." a person who complains about everything or never listens. The winner of that award gets a can of bug spray (or "pest control") Another thing is like the bathroom p award, or the person who goes to the bathroom almost everyday..and they get a bag of diapers...Well, this year, we are adding a new award called the "homework in cl" award, and because im choir president, i have to think of what the "trophy" will be. my best friend is winning it cuz shedoes her math hw in cl EVERYDAY!!! does anyone have any good ideas what to get for her. It's supposed to be funny. I was thinking of a calculator, but thats too costly
