I have been informed that the poor Marines need to raise money to afford tickets for their yearly Marine Corps Birthday Ball. You are not buying a date to the Ball, however.
Entry is free, but you can get a $5 wristband for drink specials. Starting bids are $10. There's about 20 guys and a few ladies on the auction block, so far. Looks like you get a $50 certificate towards dinner in DC if you win a date. http://www.facebook.com/USMCDet2DateAuction2014
Enjoy! Let me know if you hit it off with your Marine.
