Carolyn, a very rich blonde,

Buys a new automatic Corvette ZR1.

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 Chevy dealer and they send out a

technician to her.

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:

"Are you friggin kiddin me, 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."
