Harold and Jack are about to rob a bank. Harold says, "All right, Jack, now here's what to do: go into that bank with this gun and this bag, hold the gun on the teller and tell her to put all of the money in the bag, then run back out before the cops show up. Meanwhile, I'll be out here in the car, taking all the chances."
Jack says, "Now wait just a minute, Harold, If I'm the one running in there with the gun and the bag, getting the money and running back out before the cops show up, how are you the one taking all the chances?"
Harold replies, "Because I can't drive."
A burglar, needing money to pay his income taxes, decided to rob the safe in a store.
On the safe door he was very pleased to find a note reading: "Please don't use dynamite. The safe is not locked. Just turn the knob."
He did so. Instantly a heavy sandbag fell on him, the entire premises were floodlighted, and alarms started clanging.
As the police carried him out on a stretcher, he was heard moaning: "My confidence in human nature has been rudely shaken."
