There were twin brothers of age 5years.They had a pet cat and it was really black. Both boys loved the cat but unfortunately it was missing one day.

Both children and parents tried to find it but the effort was futile.Boys were sad and refusing to go to pre-school. But father promised to bring a new cat of same kind. Boys were happy and had been to the school.

Suddenly in the school one of the brothers were shouting to his brother "oh I have found our lost cat" so the other one followed him and looked for the brother's finding. Their teacher(lady) was seated up on a chair with wide apart legs without underpants.

Then the brother replied "no Brother our cat's mouth was horizontal , this is somebody else's cat."
