Di's little diddies

A man, wanting to rob a downtown Bank of Montreal, walked into the 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 might call the police before he reached the teller's window. So he left the Bank of Montreal and crossed the street to the CIBC. After waiting a few minutes in line, he handed his note to the teller. She read it and, surmising from his spelling errors that he wasn't the brightest light in the harbor, told him that she could not accept his stickup note because it was written on a Bank of Montreal
deposit slip and that he would either have to fill out a CIBC deposit slip or go back to Bank of Montreal. Looking somewhat defeated, the man said, "OK" and left. He was arrested a few minutes later, as he was waiting in line back at Bank of Montreal.
Don't bother with this guy's sign. He probably couldn't read it anyway
