Wrong numbers
I can understand people dialing the wrong number. We all make mistakes. I can even understand when the phone rings again moments later, only for the person to realize it's not a dialing error but they really have the wrong number. But I just can't get why the same woman called me twelve times tonight asking for the same person. The first two times I told her she had the wrong number. Then I started messing with her. But she was persistent. She just made her latest call 10 minutes ago. I was polite once again and explained that she had the wrong number, again. Whoever this guy is that she's looking for, he's got another thing comin'.

When I lived in Maine I had someone like that - they claimed that I was their son and no matter what I said or did - they'd be like "why are you fooling with us - you're so-and-so."
I stopped by the calls by holding the phone up to the TV and letting them listen in on some bad gay porn - the calls stopped real quick.
We use to have a lady that called us every night for like 2 monthes straight and we told her every night she had the wrong number. So one day my brother pretended to be the person she wanted and made plans with her. She never called back.
