Which is not to say he didn't richly deserve to get the chop. Absolutely unwilling to "lose", Howie, reaching the bottom of his limited bag of tricks, positioned himself as "choosing" to fall on his sword. Knowing that his Quickfire offering was an embarrassment, he trotted out the high-minded principle argument again (as he did in Episode One). He "chose" not to submit a less-than-the best offering -- cause he's just so exacting and his standards so high, you see.
His upturned martini glass was a defiant "Screw You" to the judges, but to me it smacked of Roberto Duran's famous "No mas" end to his bout with Sugar Ray Leonard. The tough, proud, and previously unbeatable Duran, after a few short rounds with the much faster, more polished Leonard, looked into the future and saw nothing but many more rounds of swinging at empty air and a humiliating loss on points. So he quit. Better, he figured, to walk out upright than allow anyone the satisfaction of watching him be a punching bag in the last round.
It's the old "You can't fire me! I QUIT!" exit strategy, and Howie was workin' it from early in the show. "Who gives a **** what the judges say? " he was saying -- even before he lost. In the bit from his exit interview, Howie was already at work on his revisionist version of events -- that he'd "made the right choice."
