For charity, that is. This week in stunt fundraising for the Mr. Marina contest: Candidate and tandem bike enthusiast Ben Hartard has offered to get a prison tattoo of his favorite neighborhood's postal code "on his backside" in exchange for a $1,500 donation to his campaign for the Leukemia and Lymphoma Society.

On his donation page, Ben is also offering the chance to pick what he wears in the swimsuit portion of the competition in exchange for a $500 fee. "ANYTHING GOES!" though. So if you do shell out, please be creative.

We reached out to Mr. Hartard to ask if anyone had put in any serious offers on the butt tattoo, but we have yet to hear back. Anybody want to pass the hat? This really seems like a thing that needs to happen, just to see how far these guys will go to win a male beauty pageant and a year's worth of bottomless Mimosas at Circa. It's for a good cause, after all.
