A man is sitting at his home office desk and looks out his window and notices his next door 

neighbor walk out to her mail box, open it, close it, look around then walk back in her house.

A couple minutes later he watches her walk out to her mail box, open it, close it, look around

then walk back in her house.

A couple minutes later he watches her walk out to her mail box, open it, close it, look around

this time utter some words and stand there shaking her head.

The man opens his window and asks her "Is everything alright?"

And the woman replies "No.. I think someones steeling my mail.. my computer tells me I

got mail.. then when I come out to get it..IT'S GONE!!"

 
I heard this back in my A.O.L. days
