The
                                                young man walked into the pet
                                                shop and asked if he  could
                                                buy 387 cockroaches, 18 rats and
                                                5 mice. 
                                                  'I'
                                                sorry sir, we can only supply
                                                the mice. But what did you want
                                                all those other creatures for?
                                                Asked the pet shop manager. 
                                                'I was thrown
                                                out of my flat this morning',
                                                replied the young man. And my
                                                landlord says I must leave the
                                                place exactly as I found it.
