One time when I was a teenager, I was at my brother's house. We were watching a horror movie with one of my brother's buddies. They were both cops at the time. One of the characters got into trouble, of course, and my brother's friend, trying to be funny, said, "Where's a cop when you need one?" To which I replied "They're down the street at the donut shop" They both about fell out of their chairs laughing.
