Shoes

This is a minor point, but it has always bugged me. Bobby and Greg both arrive at the wedding wearing suits, but Bobby says he "forgot" to take off his cleats, and Greg is still wearing his hospital white shoes. This implies that they put their suit trousers on over their shoes, and it also suggests that they didn't take showers prior to dressing for the wedding (which would be particularly problematic for Bobby, who had been playing baseball). The writers obviously thought this would be funny, but it doesn't make much sense.
