You Owe Me Ten Dollars

Two friends, a guy and a girl, were having a chat... Guy: Do you know I like a girl, but I don't think that she would like me. Girl: Don't worry, she will like you. I bet you ten dollars that she will definitely like you! Guy: Okay, then fine, we have a deal. (Pause) Do you like me? Girl: Nope, you are not my type. Guy: You owe me ten dollars.
