St Peter is standing at Heaven's gate when a man walks up.

"Welcome to heaven my son. What did you do with your life?"

"I was a policeman," he responded.

"What kind of policeman?" St Peter asked.

"I was a vice officer. I kept dangerous narcotics out of the hands of kids."

"Wonderful my son, welcome to heaven. Pass through the gates."

A few moments later a second man walks up.

"Welcome to heaven my son. What did you do with your life?"

"I was a policeman," he responded.

"What kind of policeman?" St Peter asked.

"I was a traffic officer. I kept the roads and highways safe for travelers."

"Well done. Pass through the gates into paradise."

A few moments later a third man walks up.

"Welcome to heaven my son. What did you do with your life?"

"I was a policeman," he responded.

"What kind of policeman?" St Peter asked.

"I was an Air Force Security Policeman, sir."

"Excellent my son... I've gotta take a pee, watch the gate, will ya?"
