When Hank jumps off of his lawn chair to chase Dale, he has shoes. During the chase, he is barefoot. When the chase is over, his shoes are back on. This first part of the goof is explained by a deleted sequence included on the DVD release of Season 1. In the complete version, it shoes Hank's shoes and socks coming off in the mud. Then Kahn tells Hank to put on his shoes as his feet were sinking in the mud. However it seems apparent that the goof of how his shoes got back on is still relevant.
