"One for me and one for Harvey"

In my never ending effort to remain hip and contemporary on all things pop-culture I bring you this bit of gossipy-stupidity:

Movie great JAMES STEWART was forced to prove he wasn't gay by bedding two hookers, according to an explosive new biography.

Movie mogul LOUIS B MAYER reportedly instructed the IT'S A WONDERFUL LIFE star to prove to him he wasn't a homosexual before offering him a film deal, sending the actor off to find a couple of prostitutes.

Why didn't he just go get blown by the then Nancy Davis?
