Hobbs surrendered another walk-off to Brown on June 29 that same year; an inside-the-park home run that ended in a play at the plate two strips later. She later admitted to Brown that she intentionally served up a couple of big, fat meatballs for him to hit. Brown couldn't care less.

A couple of TV specials also let Brown's team win, with him on the field ('It's Arbor Day, Charlie Brown' had them win in a rain-shortened game; 'It's Spring Training, Charlie Brown' has them win with a new player, to lose later on when he leaves), but that's it for wins in the strip.
Let this serve as inspiration to the Astros. You may have lost 107 games last year, but hey, that's less than 162.
