Be Careful What You Wish For

A married couple is driving along a highway doing a steady forty miles per
hour. The wife is behind the wheel.
Her husband suddenly looks over at her and speaks in a clear voice.
"Darling," he says, "I know we've been married for twenty years, but I want
a divorce."
The wife says nothing, keeps looking at the road ahead but slowly increases
her speed to 55 mph. "And don't try to talk me out of it," he says, "because
I've been having an affair with your best friend, and she's a far better
lover than you are."
Again the wife stays quiet, but grips the steering wheel more tightly and
slowly increases the speed to 65.
He pushes his luck. "I want the house," he says insistently.
Up to 75 mph.
"I want the car, too," he continues.
80 mph.
"And," he says, "I'll have the bank accounts, all the credit cards and the
boat."
The car slowly starts veering towards a massive concrete wall. This makes
him a wee bit nervous, so he asks her, "Isn't there anything you want?"
The wife at last replies - in a quiet and controlled voice. "No, I've got
everything I need," she says.
"Oh, really?" he inquires. "So what have you got?"
Just before they slam into the wall at 85 mph, the wife turns to him and
smiles. "The airbag."
