St Peter is standing at Heavens 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 travellers.

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… Ive gotta take a pee, watch the gate, will ya?
