"Dear Diary,
Last year I replaced all the windows in my house
with those expensive double pane energy-efficient
kind. Then, this week I got a call from the
contractor who installed them. He was complaining
that the work had been completed
a whole year ago and I still hadn't paid for them.
Now just because I'm blonde doesn't mean that I am
automatically stupid. So, I told him just what his
fast talking sales guy had told me last year....
namely, that in ONE YEAR these windows would pay for
themselves! Helllooooo? It'* been a year!
There was only silence at the other end of the line,
so I finally just hung up. He didn't call ba ck.
Bet he felt dumb!"

I liked that one! I'm going to have to try that.... :P
