"The NBAs are like the Oscars, except the acceptance speeches are longer and no one is attractive," an agent observed as a burbling, mostly elderly crowd gathered for cocktails outside a ballroom at the Marriot Marquis last night. Au contraire! Author-hottie Josh Ferris was looking Hollywood handsome, decked out in a tux adorned with his Finalist medal. He and Jim Shephard, who was also in contention for the fiction prize, stood shoving each other playfully and talking about how thrilled each would be if the other won. "The brutal fact is, I'm not going to win, " Josh said. He was correct: The prize went, as expected, to Denis Johnson for his Vietnam novel 'Tree Of Smoke.' But Josh quite possibly won the prize for "Having and Being the Most Fun at the Pre-Party."
