She drives the car perfectly well during the day, but at night, the car just won't move at all.
After trying to drive the car at night for a week (but without any luck), she furiously
calls the Jaguar dealers and they send out a technician.
The technician examines the car and finds nothing wrong with it. So he turns to the blonde
and asks:
"Ma'am, are you sure you are using the right gears?"
Full of anger, the blonde replies:
"You fool, you idiot, how on earth you could ask such a question? I'm not stupid you know!
Of course I am using the right gears;
I use D during the day and N at night."
