Springfield Isotopes T-shirt
Some visiting teams complain that having four arms to catch a ball is unfair play, but hey, you don't get to choose the radiation level of your neighborhood, do you?
Nevertheless, the Springfield Isotopes are the only team known to have triggered an atomic meltdown after a homerun. Some say the ball got stuck in a turbine at the nuclear facility outside the stadium, but locals claim the hitter was just explosive that day.
