ok my turn: i worked a prominent spa for 5 years and saw many celebrities in the buff.
i was a manager and part of my rounds were to walk the locker rooms and inspect the locker room attendant's work and there are naked men in the locker room. we hosted some celebrities there: neil patrick harris, tony danza, pauly shore, chris evans, matthew lillard, jared leto (didn't see and penis only his butt), jordan knight, the cast from rescue me, lance bass and reichen (when they were newly dating) and the cast of the sopranos.
pretty awesome job i must say
