Martin was a slow worker and found it difficult to hold down a job. After a visit to the job centre 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 section. 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!"
