Oscar enters the Grouch Auto Show

Big Bird discovers how to make paper airplanes from a library book and announces plans to create one with Snuffleupagus, much to the amusement of David and Gordon. A massive paper airplane suddenly soars through the air and crashes into Hooper's Store, sent by Snuffy with his \"medium-sized paper.\" David and Gordon debate whether the mysterious airplane proves Snuffleupagus exists while Big Bird grins at their confusion.
