Lem: "I got fired from my job as a bank guard."

Clem: "That's awful. What happened?"

Lem: "Well a thief came in to rob a bank. I drew my gun. I told him that if he took one more step, I'd let him have it."

Clem: "What did thief do then?"

Lem: "He took one more step so I let him have it. I didn't want that stupid gun anyhow!"
