Last year I replaced all the windows in my house with those expensive, double-pane, energy-efficient kind.

Today, I got a call from the contractor who installed them. He complained that the work had been completed a year ago and he still hadn't been paid for them.

Hellloooo,............just because I'm blonde doesn't mean that I am automatically stupid. So, I told him just what his fast-talking sales guy told me last year... that these windows would pay for themselves in a year,,, Helllooooo? It's been a year, so they're paid for, I told him.. There was only silence at the other end of the line, so I finally hung up.
He never called back.
I bet he felt like an idiot...
