What Houston witnessed on the train today

Today, as Houston was taking the train home, the cops were going through checking tickets. One reprobate did not, in fact, have a ticket. He showed his ID, and murmured something vague about having to get out at the next stop. "Sure, mate," said one of the cops.

As the train slowed and the guy turned to open the door, the cop said casually, "Hey, mate, you dropped your little drug packet."

The guy gave a horrible start and looked wildly around the floor of the carriage. "What?"

A pause.

Then the other cop said, "Right, mate, you and I are getting out here."

As they stepped out onto the platform, the first cop said, "Jeez, I only wanted to embarrass him."
