Plot

The Boy meets and marries The Girl. A year later, the two walk down the street with a baby carriage carrying a bottle instead of a baby when they run into The Girl's brother who asks the couple to do him a favor and babysit his children. They accept and the remainder of the short consists of gags showcasing the difficulties of babysitting children. At the very end, The Boy discovers some knitted baby clothes in a drawer (implying that The Girl is pregnant).
