A skunk family had two little skunks they called In and Out.
One day little In disappeared. Mother Skunk, Father Skunk and young Out spent
hours looking for him, getting more worried all the time. In the end the parents
went home to have a cup of tea, but Out said he'd continue searching for a while.
Half an hour later he returned home, with a tired In following behind him.
'However did you find him?' asked Father Skunk.
'In-stinct,' replied Out.
