This one sent to me by my sister a while ago:
I went to the store the other day, and I was in there for only about 5 minutes. When I came out there was a motorcycle cop writing a parking ticket. So I went up to him and said, "Come on, buddy, how about giving a guy a break?" He ignored me and continued writing the ticket. So I called him a pencil-necked Nazi. He glared at me and started writing another ticket for worn tires! So I called him a piece of horse s**t. He finished the second ticket and put it on the windshield with the first. Then he started writing a third ticket! This went on for about 20 minutes... the more I abused him, the more tickets he wrote. I didn't care. My car was parked around the corner. I try to have a little fun each day. It's important.
