On show and tell day at school, everyone has brought something fun and exciting to school, and Bert especially wants his to be a surpise. After play time, story time, and paint time, it is time for show and tell. Cookie Monster has brought his collection of cookie cutters, Rodeo Rosie shows the lariat her cousin Duane brought her from Oklahoma. Ernie plays on his drum, Grover and Prairie Dawn demonstrate their tin can telephone, Herry Monster shows off his dancing shoes and Farley has a rubberband airplane.
When Bert goes to open his surprise, he is shocked to discover that Bernice, his suprise for show and tell, has escaped. Everyone searches the classroom, and they soon find footprints from wet paint that Bernice had walked across. But they can't catch her; she just flies around the room and stays out of reach.
Betty Lou reveals her show and tell object, a loaf of peanut butter raisin bread that she had made herself. She uses it to make a trail of breadcrumbs to Bernice's box, and soon Bert's pigeon is safe and sound. The class celebrates by having some of Betty Lou's bread.
