Once upon a time, there was a family of skunks; Mr Skunk, Mrs Skunk and their two twin boys, In and Out.

One day, while Mr Skunk was at work and Mrs Skunk was home with the kids, she realised that she needed some groceries from the store. So, she said to In and Out, "In, Out, I need to go out so I want you two, In and Out, to stay in while I'm out. Okay?"

"Okay," replied In and Out. "We'll stay in while you go out."

And so, Mrs Skunk went out, leaving In and Out in. After a while In became bored being in so In went out.

Not long after, Mrs Skunk came home to find Out in and no In. She said to Out, "Where's In?"

Out replied, "In's out."

Mrs Skunk shook her head and waved at the door. "Out, Out." she told Out, "And don't come back in until you've found In and brought In in."

So Out went out to look for In. He looked here and there and, not being able to find In, he went back in.

"I can't see In," he reported.

Mrs Skunk wasn't going to stand for this. "Out, you go Out and bring In in or by golly, you'll both be grounded for a week!"

So Out went out again. Moments later, Out came back in with In.

Mrs Skunk frowned at In. "In, in your room. I'll deal with you in a minute." She turned to Out. "Out, how did you find In so quickly when a minute ago you said couldn't find In?"

Out shrugged and replied, "In stinks!"
