You need to join the Army of the Lord!

A friend was in front of me coming out of church one day, and the priest was standing at the door as he always is to shake hands. He grabbed my friend by the hand and pulled him aside.

The Priest said to him, "You need to join the Army of the Lord!"

My friend replied, "I'm already in the Army of the Lord, Father."

Priest questioned, "How come I don't see you except at Christmas and Easter?"

He whispered back, "I'm in the secret service."
