There were three children called Zip, William who everyone including the teachers called Willy, and Pedro, who everyone called P, even the teachers.
they always messed around, getting into trouble.

One day, when the teacher left the class, everyone did as they were told, but Zip, William and Pedro were messing around.

When the teacher came in, she saw Zip on top of the filing cabinets, William in them and Pedro kicking them.

The teacher was not happy and yells out:

Zip down, Willy out, and P in the corner!
