A mother skunk gave birth to twins, whom she named In and Out.
One day In was out, so she asked Out,”Out go out and find In, In’s out and I want him in, I’ve been looking for In outside for ages, I can’t find In, he is out so go out find In and bring him in.”
“What?” said Out.
“In’s out, so Out go out find In and bring him In, I’ve been looking for ages and can’t find In, I want In in, Out, go out and bring In in, if you can find him.”
So Out goes out to look for his brother In, and within seconds of leaving, he comes back with In in tow, and his mother asks “Out, how did you find In so quickly?”
“In stinkt.”
