Tank (Dane Cook) has a gift – he can make any girl think he is the biggest moron in the world.
He turns this special skill into a profitable sideline, getting guys to pay him to take their ex-girlfriends on a date and treat them so bad that they will instantly run back to their old boyfriends. However, when his best friend Dustin (Jason Biggs) asks him to do the same with Alexis (Kate Hudson), Tank finds himself falling for her. Cook is in his element in this coarse romantic comedy, where he manages to be both incredibly offensive and endearing. The plot takes a predictable turn in the second half, but this doesn't prevent the swearing and the tastelessness continuing right up until the credits.
