I'd heard about this bit of Phillies fandom last week:
On the XM RadioBaseball This Morning: Playoff Edition today, a caller from Delaware chimed in to share his joy for the Fightins. He may have just created the next great new catch phrase, saying, "Boston did it. The White Sox did it. Why can't us? Why can't us." 2008 Philadelphia Phillies: WHY CAN'T US!
Awesome. No really, I mean it. But I didn't realize that grammatically incorrect could unite a city until today, when Bill Brohaugh of Everything You Know About English Is Wrong pointed to this Yahoo story:
The slogan was taken from a grammatically-challenged sports radio caller — yes, I realize that is redundant — and it has already grown so large that Scott Van Pelt reportedly dropped it on Sports Center last night. Expect to be seeing a lot of these over the next week or so.
