Old Mr. Pippin discovers his rusty mailbox has grown a magnificent, fluffy, handlebar mustache. His neighbor, Mrs. Gable, doesn't notice anything unusual, but Mr. Pippin soon learns the mailbox is a budding artist who created the mustache as its first piece of "art." Mr. Pippin accepts the mailbox's whimsical creativity but asks that it not grow a giraffe out of flowers next week.
