Pig With Wooden Leg

The MP was making his rounds through the Sembawang kampung area. In Ah Chye's
kampung house, the MP noticed a pig with a wooden leg hobbling about. 
"Excuse me," the MP said to ah Chye, "but why does that pig
have a wooden leg?" 
"Oh, it's like this, sir... one night a robber entered our household,
tied all of us up, stole our jewelry and was about to escape when the pig came
out of nowhere, attacked the robber and saved us all." 
"Oh, I see," said the MP uncertainly, "but I still don't
understand. Why does the pig have a wooden leg?" 
"Oh, it's like this, sir... There was a fire when we were all out to the
cinema at Chong Pang. The pig alerted our neighbors, ran around organizing a
water bucket system and helped the firemen put out the fire." 
The MP was getting quite frustrated. "Listen, Mr Chye, That is all very
interesting, but I still don't understand why the pig has a wooden
leg." 
"Oh, it's like this, sir..." Ah Chye said. "We used to have an
old well. One day, our little daughter fell down the well. The pig jumped in,
saved our girl, covered the well with planks and we never had that trouble
again." 
The MP shouted, "I DON'T UNDERSTAND! Why does that damn pig have a
wooden leg?" 
Ah Chye appeared absolutely unfazed. "Well, you know," he said
finally, "with a pig that good, how can you eat it all at once..."
