Are you in college? Do you enjoy making life generally more pleasant for others? Are you allergic to shirts? If you answered "yes" to all these questions, you're a perfect candidate for Hilarity For Charity's HFC U challenge, called "Kick Alz in the Ballz."

Zac Efron and Seth Rogen, who are promoting the contest, are requesting that this school year, you "enroll in HFC U" -- a division of Hilarity for Charity that encourages college students to raise awareness -- and funds -- for Alzheimer's disease research. "For every $10 that a student fundraises through CrowdRise, he/she will receive one entry to win a trip for two to Atlanta to take a shirtless photo with Seth Rogen and Zac Efron on the set of 'Neighbors 2,'" a rep said in a statement to the press. (Note: you can keep your shirt on if you want, that's totally cool.)

Let Zac and Seth explain a little further:

The contest opens Wednesday (September 2) at 2 p.m. ET and closes on Saturday, September 19 at 12 p.m. ET. You must be a college student to participate.

You can enroll in HFC U here.
