And by the way . . . it has become such an ingrained part of "Cubbishness" that fans are expected to throw back opposing player's home run balls, that many fans bring baseballs to the park so if they are lucky enough to catch a home run ball, they can throw back the fake ball, and not be harassed by the bleacher bums. Of course, its also a tradition at Wrigley Field if the fans don't like an umpire's call, or some similar happening, the fans shower the field with trash. Its good to be a Cubs fan. Classy bunch.
