Donnie drags Paul on a last minute trip to check out the site of the new Wahlburgers' Las Vegas location. After their work is done, Donnie tries to get his unlucky brother to loosen up at the casinos--and prays that Paul's jinx isn't contagious. Back home, Mark takes a gamble of his own when he and his lookalike nephew Brandon place a bet on a one-on-one basketball game between Nacho and his very own mini-me, Brandon's friend, Pat.
