Zach Graham

Two days before his wedding, Doug (JUSTIN BARTHA) and his three friends (BRADLEY COOPER, ED HELMS and ZACH GALIFIANAKIS) drive to Las Vegas for a blow-out bachelor party theyll never forget. But, in fact, when the three groomsmen wake up the next morning, they cant remember a thing. For some reason, they find a tiger in the bathroom and a six-month-old baby in the closet of their suite at Caesars Palace. The one thing they cant find is Doug. With no clue as to what transpired and little time to spare, the trio must retrace their hazy steps and all their bad decisions in order to figure out where things went wrong and hopefully get Doug back to L.A. in time to walk down the aisle.
