The Naked Karate Girls? They’ll be joining local bands Doghouse and Marsha Brady in entertaining more than 3,000 young professionals on Dec. 11 at the 25th Annual World’s Largest Office Party in the Hyatt Regency Ballroom. This year the party goes even later — from 5 p.m. to 1 a.m. Proceeds (including a silent auction) benefit the Muscular Dystrophy Association of Cincinnati. Tickets are $10 and can be purchased at the front desk of the Hyatt after Dec. 1. Or, you may call MDA at (513) 231-2222, e-mail or show up the door.
