Mary Simpson was almost crazy with her three kids.

She complained to her
best friend, "They're driving me nuts. Such pests, they give me no rest,
and I'm halfway to the nut house."

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

So Mary 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!"
