A woman complained to her best friend, "They're driving me nuts. They give me no rest and I'm pulling my hair out."

"What you need is a playpen to separate the kids from yourself." her friend suggested.

So she bought a playpen. A few days later, her friend called to ask how things were going.

"Superb! I can't believe it." Mary said. "I get in that pen with a good book and the kids don't bother me one bit!"
