Ah Beng, Mohammad and Muthu were at sea when they were hijacked by a group of pirates. 
The pirates cornered the 3 men and said "Give us all your valuables!" The chief pirate then raised a syringe and added, "Or else we'll inject you with the AIDS virus!" 
Mohammad quickly stripped off all his valuables and handed them to the pirates. Satisfied, they threw him into the sea. 
Muthu was equally quick to comply with the pirates' wishes. Similarly, he removed his valuables and surrendered them to the pirates. Like Mohammad, he was thrown into the sea. 
Finally it came to Ah Beng's turn. He stared at the pirates and sneered. "You all kee see lah! (go and die!) Inject, inject lah, you'll never get my lolex and my JPG
warret!" 
The pirates, showing no mercy, injected Ah Beng with the HIV virus, and robbed him of his precious watch and wallet. They then threw him into the sea with the rest. 
In the water, both Mohammad and Muthu commended Ah Beng for his bravery. However, they were pretty perplexed by why he was unafraid of the virus. Grinning, Ah Beng answered, "AIDS I not scared, what... I got condom!!!"
