Catching fish

A man was speeding down the highway, feeling secure in a gaggle of cars all traveling at the same speed. However, as they passed a speed trap, he got nailed with an infrared speed detector and was pulled over.

The officer handed the man a citation, and then as he turned to walk back to his cruiser, the man asked, "Officer, I know I was speeding, but I don't think it's fair. There were plenty of other cars around me going just as fast, so why did I get the ticket?"

"Ever go fishing?" the policeman asked the man.

"Um, yeah... so," the startled man replied.

The officer grinned and added, "Ever catch ALL the fish?"
