our kids' elementary would do this, it was a great PTA fund-raiser... every family from Teacher ABC's class would donate something for the theme... one year we had a "movie night basket" which was tallied at over $260 value... loaded with DVDs, theatre tickets, popcorn, giftcard for Blockbuster, etc... people were buying extra tickets to try and win it, and our PTA used the funds to send the whole graduating class to a minor league baseball game (Akron Aeros) for a day (whole class/grade outing). These are so fun!
