Have you ever been so bored sitting at home that you actually get excited when the phone rings? Then you find out that the person on the other end accidentally dialed the wrong number but you still try to keep them on the line just so you don't have to go back to being bored?
"I'm sorry you have the wrong number but do you want to talk anyway? Please just talk to me for a little while. You don't understand, I'm bored. No, No, wait, I'm only kidding. This is Bob, I was just joking with you. I swear it is. What's my last name? Come on you know what my last name is. No, please don't..." CLICK! "...hang up."
It's no wonder 1-900 numbers get so much business. You're bored out of your mind sitting at home with absolutely nothing to do...and...well...
"Helloooo, this is Rachelle. What's your name?"
"Umm, err, this is Bob, and don't ask me my last name."
