Ah Beng All Wet

Last night, an incident took place at Boat Quay. What happened was some idiot was trying to show off and declared that he would swim across the Singapore River. He jumped in and started swimming. But before he could reach the halfway mark, he started to panic and started to shout for help.
Being typical Singaporeans, a crowd started to gather to watch and yet no attempt was made by anybody to save that poor chap.
Suddenly there was a splash and the crowd turned to see a guy doing what seemed like a desperate attempt to reach the drowning victim. It was clear that this hero couldn't swim !
Luckily a tongkang filled with tourists was passing by and the operator saw the incident and picked both men from the water. The crowd cheered !
Back on shore, the crowd cheered again as the hero stepped off the tongkang. "Steady Lah !" and "Awright, man !" were among the many congratulations shouted. 
The hero looked angry and shouted "Ka ni na! Siang too wa loh chui?" (*%#@! Who pushed me into the water?")
