Ben Stone (Seth Rogen) is a 23-year-old slacker who is in the process of establishing fleshofthestars.com, a website that lists the exact moment in time at which nude scenes with famous actresses occur in films. Alison Scott (Katherine Heigl) is a responsible young woman who works behind the scenes at E! Television Network. Although she is on the career fast track, she lives in the pool house behind her sister Debbie's home, and plays an active role in helping her and her husband Pete raise their daughters. Alison and Ben find themselves at the same club where she is celebrating her promotion at E! with her sister. They begin drinking together, and she invites him back to her pool house. The next morning, they learn that they have very little in common. Eight weeks later, Alison begins feeling very sick and comes to the conclusion that she is pregnant, and she contacts Ben. She tells Ben that she is pregnant and that she has decided to keep the baby. Ben's initial response of shock and anger mixed with Alison's frustrations creates tension, resulting in Ben agreeing to take Alison to confirm the pregnancy.
