Taglines: He finally found the perfect girl.

Karen (Selma Blair) and Paul (Jason Lee) are about to get married. During his bachelor party, Paul has a chat with one of the dancers at the party, Becky (Julia Stiles) and they find that they have an affinity for each other. Paul wakes up the next morning and is terrified to see Becky in the bed next to him. Assuming they slept together, Paul rushes Becky out of his apartment and hopes never to see her again.

He tries to cover up the connection for the few days before the wedding. Unfortunately, Becky unexpectedly shows up around town and turns out to be Karen’s cousin. Even worse, Becky’s ex-boyfriend cop Ray had Becky followed and photographed. Becky and Paul meet again to steal those pictures from Ray’s apartment. Further problems arise with family and friends consistently showing up at the wrong times. Crabs, dirty underwear in the toilet tank, a horny best friend, and a best man/brother who is in love with the bride all provide for a week of wedding preparation hijinks.

Through the snowballing of all his implausible lies and half truths, he receives corroboration and support from an unexpected corner: what seems to be a coordinated network of other men, including friends, complete strangers and to Paul’s astonishment, Karen’s own father; all who give the same explanation: “It’s a guy thing”.
