In San Francisco, a man, wanting to rob a downtown Bank of America, walked into a local branch and wrote, "this iz a stikkup. Put all your muny in this bag."
While standing in line, waiting to give his note to the teller, he began to worry that someone had seen him write the note and that they might call the police before he even reached the teller window. So he left the Bank of America and crossed the street to Wells Fargo.
After waiting a few minutes in line, he handed his note to the Wells Fargo teller. She read it, noticing all of his spelling errors. She quickly surmised that he wasn't the brightest light in the harbor.
Then she told him that she could not accept his stickup note because it was written on a Bank of America deposit slip and that he would either have to fill out a Wells Fargo deposit slip or go back to Bank of America.
Looking somewhat defeated, the man said "OK" and left. The Wells Fargo teller then called the police who arrested the man a few minutes later, as he was waiting in line back at Bank of America.
