A while ago there was a post about things or verbage that 'bothers' individuals. I was listening to a TV ad today and the talking head said to call a telephone number. He said: "Call 555-123-23"Oh"5. If you dial exactly what he said you would dial 555-123-2365. The LETTER "O" is a number "6" on a phone dial. The proper term is "ZERO" not "Oh".
