A man was driving and came to a stop sign. He slowed down long enough to check if any cars were coming, and then proceeded through the intersection.

A police officer saw it happen, and pulled the guy over.

The man asked, "what did I do, officer?"

"You ran that stop sign over there," the officer said.

"No, I slowed down!" the man said.

"But you didn't stop," said the officer.

"Slow down, stop, what's the difference?!" asked the man, getting agitated.

The officer took out his nightstick and started to poke the guy in the chest. "Now," said the officer, "do you want me to slow down or do you want me to stop?"
