Fishing
One day Mahathir and Lee Kuan Yew went fishing together. Mahathir ended up with full bucket of fishes while Lee Kuan Yew stared at his empty bucket. So Lee asks Mahathir,"How did you manage to get so many catches? What's your secret?"
Mahathir smiles and says,"Well you never allow the fishes to open their mouths; you'll never catch them in this way. For me, once the stupid fish open its mouth, I catch!"
