Larry and Jeff are in the championship softball game and are one out away from winning when a Mister Softee truck pulls up near the park. Larry loses his concentration and lets the ball roll through his legs a la Bill Buckner, and loses the game.
We find out Larry was traumatized as a kid when he played strip poker with a girl in a Mister Softee truck, and ended up having to walk outside in front of everyone completely naked.
Susie tells Larry to get Jeff a signed Mookie Wilson baseball for his birthday. When he goes to get it, he meets Bill Buckner and they bond over similar experiences. They end up outside a burning building and a lady throws her baby out the window. Buckner ends up making a diving catch to save the baby and is revered by everyone.
