Number, Please?(1920)

While at an amusement park, trying vainly to forget the girl he has lost, a young man sees the girl with her new boyfriend. When her dog gets loose in the park, both suitors have to help her catch it. Then, the girl's uncle, a balloonist, gives her a pass for two in his balloon, provided that her mother approves. She then offers to take along the first of her admirers who is able to get her mother's consent.
