What did the Blonde say to the Window Installer?

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

Yesterday, I got a call from the contractor who installed them. He was complaining that the windows had been installed a whole year ago and I hadn't paid for them yet.

Now just because I'm blonde doesn't mean that I am automatically stupid.

So I told him just exactly what his fast-talking sales guy had told ME last year: Namely that in just ONE YEAR these windows would pay for themselves!  'Hel-looooo!!' (I told him). 'It's been a year!'

There was only silence at the other end of the line, so I finally just hung up . . .  He hasn't called back.

Probably too embarrassed about forgetting the guarantee they made me.  Bet he won't underestimate MY intelligence again.
