Martin was a slow worker and found it difficult to hold down a job. After a visit
to the job center he was offered work at the local Zoo. When he arrived for his
first day, the keeper aware of his reputation told him to take care of the tortoise
Later, the keeper dropped by to see how Martin was getting on and found him standing
by an empty enclosure.
"Where are the tortoises?" he asked him.
"I can't believe it" said Martin "I just opened the door and then.....Whooooosh!"
