This is the joke that came to mind:
Two boys are playing football in Central Park when one is attacked by a rabid Rottweiler. Thinking quickly, the other boy rips off a board of the nearby fence, wedges it down the dog's collar and twists, breaking the dogs neck.
A reporter who was strolling by sees the incident, and rushes over to interview the boy.
"Young Giants Fan Saves Friend From Vicious Animal," he starts writing in his notebook.
"But I'm not a Giants fan," the little hero replied.
"Sorry, since we are in New York, I just assumed you were." said the reporter and starts again. "Little Jets Fan Rescues Friend From Horrific Attack" he continued writing in his notebook.
"I'm not a Jets fan either," the boy said.
"I assumed everyone in New York was either for the Giants or Jets. 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 Redneck Maniac Kills Beloved Family Pet."
