There was a blonde who got instructions mixed up all the time.  
When she got married her husband bought her one of
those fancy, electric coffee makers.  It had all the latest
gadgets on it.
A salesman carefully explained how everything worked;
how to plug it in, set the timer, go back to bed, and upon rising,
the coffee is ready."
A few weeks later the blonde was back in the store and the salesman
asked her how she liked the coffee maker.

"Wonderful!" she replied, "However, there's one thing I
don't understand.   Why do I have to go to bed every time I want
to make a pot of coffee
