What is a good incentive to get kids to vote ?

My school is holding a mock election for the coming election. Its held on the same day as the real one, and im in charge of finding a incentive to get students to show up, because it takes place before or after school. This is a high school, so if you can think of anything CHEAP, cause we have a small budget, then please answer thanks.

Tell them by the time they become Senior citizens they wont able to get social security. That alone will scare them to show up. Vote for Obama
Candy.... lol..... seriously... kids will do anything for candy.
A free night with Palin...she'll do anything and put anything in her mouth
How about offering a small breakfast before school and a small snack after.
Show them images of the flag draped coffins coming back from Iraq and tell them if just a few more people had voted for Gore these soldiers would still be alive and not dying needlessly in Bush's war. How we vote is truely a matter of life and death for our brave military personnel.
Ask teachers to give them a "no homework" slip. If they vote, they don't have to turn in homework the next day. If they don't vote then homework is due.
Show a picture of McCain's face. They will have to vote for Obama. GOBAMA!!!!!!!! McBush sucks!!!!!!
