Some nutter walks into an eastern Michigan bank and hands the teller a note saying he’s got a bomb on him and he wants money. A customer gets wind of this, pulls a pistol on the man and informs him he’s not robbing the bank. Nutter responds that he’s got a bomb. Customer responds with, “I don’t care.”
Turns out the nutter didn’t have a bomb anyway, so that’s good. The customer with the concealed weapon made him sit on a chair until police arrived.
