The day after my birthday, I was sitting at my desk at work and got a phone call from a number that I didn't recognize. The female voice on the other end of the phone began to sing happy birthday. She sang about three quarters of the song and then said something about, "Oh you dont really have to put up with my singing." She then said, "Happy birthday" and something like, "how are you?" I said fine and we exchanged pleasantries and chatted for a moment or two. I was trying to place the voice but really had no idea who it was, so I admitted it and said, "Um... I'm sorry, but I just don't have any idea who this is." And she said. "Of course you do, who else would talk to you like this? (pause) It's your sister!!!" I replied with, "Um... Who do you think this is?" She said, "Isn't this Ken?" "Nope, my name is Peter, but yesterday was my birthday...." Hilarity ensued.

My first and only Happy Birthday Wrong Number......
