"Dear Diary,
 
Last year I replaced all the windows in my house with that expensive double-pane energy efficient kind.  But 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 hadn't paid for them.
 
Helloooo!   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's been a year! (I told him.)
 
There was only silence at the other end of the line, so I finally just hung up.... He didn't call back."
 
(. . .  just for fun :-)
