Ah Beng & Ah Lok rented a  boat and went fishing. On one  particular day, they caught 30 fishes. Ah Beng said to Ah Lok, 'Mark this spot so that we can come back here again to fish tomorrow.'  The next day, when they were driving to rent the boat, Ah Beng asked Ah Lok, 'Did you mark that spot yesterday ?' Ah Lok replied, “Yeah, I put a big X on the bottom of the boat.'

Ah Beng was furious and said , 'You stupid fool! What if someone rent the boat, we have no chance lah”.
