Here’s How Zac Efron’s Abs – And Yours – Can Make The World A Better Place

Stripping down never felt (or looked) so good.

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.
