Date and Switch - S3.E25

Wyatt has a fear that Marlowe could break up with him after they've gotten on each other's nerves for a while. Caitlin meets a cute boy named Calum at a party and later realizes he's a nerd so she writes him a fake phone number, but she writes the number on the back of her very own Khaki Card, on which she saved shopper's card points since she was 14 years old. So Caitlin needs to find a way to search for Calum and get her Khaki card back.
