A Guy Thing

Paul Coleman (Jason Lee) is a good guy. When his friends throw him a wild bachelor party, he just wants to keep his conscience clean - which is why he's shocked when he wakes up in bed with a girl named Becky (Julia Stiles) and can't remember the night before. Worse than that, she also happens to be his fiancee's cousin. Desperate to keep his fiancee Karen (Selma Blair) from finding out what may or may not be the truth, he tells her a teensy lie. Which turns into a bigger lie. From the bachelor party to the wedding, soon his lies are spiraling out of control and his entire life is a series of comical misunderstandings.
