Windshield wipers slappin' out a ten-four, keeping perfect rhythm with the song on the radio.

The story:

I had made a comment about a post on the social networking site "Facebook". A well known artist had stated that they had been through a bad rainstorm and were almost home. I asked her if the "windshield wipers were slappin' out a ten-four", with several comments following about the mistake. The sad part is that I have been a radio DJ for 14 years.
