Philadelphia Joke

Two boys are playing hockey on a pond in Fairmont Park when one is suddenly attacked by a rabid rottweiler.
Thinking quickly, the other boy takes his stick and shoves it under the dogs collar, twists it breaking the dog's neck and saving his friend. A reporter who was strolling by sees the incident. "Flyers Fan Saves Friend From Vicious Animal," he starts writing in his notebook. "But I'm not a Flyers fan," the little hero replied. "Sorry, since we are in Philadelphia I just assumed you were," said the reporter and he starts writing again. "Eagles Fan Rescues Friend From Horrific Attack." "I'm not an Eagles fan either," the boy said.
"Oh, I assumed everyone in Philadelphia was either for the Eagles or the Flyers. What team do you root for?" the reporter asked.
"I'm a Cowboys fan," the child said.
The reporter starts a new sheet in his notebook and writes, "Little Bastard From Dallas Kills Beloved Family Pet."
