A $436,000 slots jackpot - and the two quarters Richie bummed from Evan to win it - set in motion a hip, funny tale of devious retaliation and outlandish consequences from film-debuting writer/director Larry David, the co-creator of "Seinfeld." Girlfriends, a smothering mom, a preening sitcom star, an upwardly homeless man- and others join the comic character parade that helps make Sour Grapes so bitterly, outrageously sweet.
