Marvin Williams, designated driver, wanted to play a joke late Sunday night.
So he put a flashing red-blue light on the dashboard of his friend's Ford Expedition and pulled behind a car driving south on North 36th Street, police say.

It was one of a series of bad moves, police say.

The first? Choosing a car with two undercover Tampa officers in it.

It didn't help much when he laughed about it as he drove by.
