Joe is at the Pearly Gates waiting to be admitted while St. Peter is leafing through his files to see if Joe is worthy of entry.
"Joe," says St. Pete, "I can't see that you've done anything really bad in your life but I can't see that you've done anything really good that would qualify you for Heaven. Can you tell me ANY good deed you've ever done?"
Joe thinks for a moment and says "Sure. I was driving through a bad part of town when I saw about 50 biker guys assaulting this poor girl. I slammed on my brakes, grabbed a tire iron, and walked up to this big guy who seemed to be the leader. All these guys let the girl run away and they formed a circle around me to see what I was gonna do. I laid that tire iron right across his head and he dropped like a stone. Then I turned and yelled to the rest of them "If I ever see you guys around this town again, I'll give you a real lesson in pain."
"Wow" says St. Peter, "I guess you really do qualify for Heaven. Tell me, when did this happen?"
"Oh", says Joe, "about two minutes ago."
