My girl friend Janie and I did the prank phone calls too. We lived in a small town, so didn't want to call anyone we might know, so we saw a cardboard box with numbers on it and put the towns prefix with it and called. Later when we wanted to call again we had to dig the box out of the trash, to get the number again. Days later. It was an old lady. She thought she knew us. We felt so bad, we had to call later and tell her. Then she didn't belive us and thought we were still her friends pulling a trick on her. My friend Janie did befriend her and stayed friends with this woman untill her death many many years later.

Wonder what makes us do these things
