Last year I replaced all the windows in my house with that expensive double pane energy efficient kind, and today, 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.

Helllooo,....... Just because I'm blond doesn't mean that I am
automatically stupid. So, I told him just what his fast talking sales guy had told me last year, that in ONE YEAR these windows would pay for themselves!

Helllooo? 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 never called back. I bet he felt like an idiot.
