11 - 21: Roads to Vegas

Stewie and Brian use Stewie's time machine to go to Las Vegas for a Bette Midler concert, but chaos ensues when the machine malfunctions and creates alt-versions of the pair: a "lucky" version and an "unlucky" one. Then, the Griffins are invited to join the prestigious Barrington Country Club and, of course, get thrown out.
