It's a bit puzzling at first, but not if you think about it. You see kids, Charlie Manuel is from West Virginia. There's a very good chance that Cousin Eddie, following his Christmas vacation at Clark's house, ditched the farm in Kansas and drove his motor home directly to Northfork, where he met Charlie. It's all making sense now. We're guessing in exchange for the shoes, Eddie received one of Sal Fasano's ass-melting leisure suits.
Update: Those are actually the shoes of broadcasting legend Harry Kalas. The Phillies keep them in the dugout, along with a blue blazer, in his memory for each game. We had no idea, although probably should have. With that said, we love Kalas even more now knowing those were his shoes.
