Say It Isn't So is a 2001 American comedy film starring Chris Klein and Heather Graham as two young lovers who come to believe that they are actually siblings. The film is directed by J. B. Rogers and written by Peter Gaulke and Gerry Swallow.
Gilbert Noble (Chris Klein) takes a stray cat named "Ringo" to the animal pound where he works. Gilbert gets his haircut by a beautiful young hairdresser named Josephine "Jo" Wingfield (Heather Graham). As Jo cuts Gilbert's hair, she mentions that she lost a tail-less cat named Ringo a while ago, leading Gilbert to tell her that Ringo is at the pound. Immediately after this revelation, Jo accidentally cuts off a part of Gilbert's ear, and he is rushed to the hospital. To make up for the incident, Jo invites Gilbert to her house for lunch the next day, where Gilbert meets Jo's self-centered mother, Valdine (Sally Field), and stroke-suffering father, Walter (Richard Jenkins). After lunch, Gilbert and Jo start dating, and fall in love. Gilbert and Jo eventually have sex for the first time. Just as Gilbert prepares to propose to Jo, he receives a call from a detective (Brent Briscoe) who has been searching for Gilbert's long-lost mother.
