"There is always something intriguing and stimulating about the ringing of a telephone bell. Will this, we ask ourselves, be the girl we love, or will it be somebody named Ed who, all eagerness to establish communication with someone named Charlie, has had the misfortune to get the wrong number? Jerry, though always glad to chat with people who got the wrong number, hoped it would be Penny." (from Pigs Have Wings, by Sir Pelham Wodehouse)
I once had a lady call our number at work, and it took me five minutes of steady back-and-forth to convince her that this was not the jail, and that I had no idea when the man of her dreams was going to get out of jail.
