A distinguished gentleman comes out of the synagogue one Saturday.
The Rabbi was standing at the door as he always is to shake hands. He grabs the gentleman by the hand and pulls him aside.
The Rabbi says to him, "You need to join the Army of G-d! "
The gentleman replies, "I'm already in the Army of G-d, Rabbi."
The Rabbi questions, "How come I don't see you except on Yom Kippur and Yizkor?"
The gentleman whispers back, "I'm in the secret service."
