Alex and Rick decided to rob a bank together. Alex plans the robbery and goes over the plan with the Rick, in great detail.
Alex drives up in front of the bank, stops the car and says to Rick, "I want to make absolutely sure you understand the plan. You are supposed to be in and out of the bank in no more than three minutes with the cash. Do you understand that."
"Perfectly," said Rick. Rick goes in the bank while Alex waits in the getaway car. One minute passes... Two minutes pass... Seven minutes pass... and Alex is really stressing out.
Finally, the bank doors burst open! And here comes Rick. He's got a safe wrapped up in rope and is dragging it to the car.
About the time he gets the safe in the trunk of the car, the bank doors burst open again and the security guard comes out, his pants and underwear around his ankles and firing his weapon.
As they are getting away, Alex says "You are such an idiot! I thought you understood the plan!"
Rick said, "I did... I did exactly what you said!"
"No, you idiot," said Alex. "I said tie up the GUARD and blow the SAFE!"
