A blonde and a brunette decide to rob a bank. The brunette explained the plan to the blonde and the blonde reassured the brunette that she knew the plan.
So they drove to the bank and the brunette kept the car running and the blonde ran in to start the robbery.
The brunette sat in the car for 10 mins then 20 then 30. Then running out of the bank came the blonde dragging along a safe tied up with a rope and behind came running a security guard with his trousers around his ankles trying to reach his gun...
The blonde just dropped the safe and jumped in the car panting.
The brunette says to the blonde, "what happened in there. I told you TO TIE UP THE GAURD AND BLOW THE SAFE!"
