Thanks to Facebook. I dropped this question to my Facebook status and my friends have answered. Collating all the ideas and trying to put them in practice. I first tried to poke into the head as suggested. May be my chopstick isn't long enough, the crab was still very active and trying to escape!
Without too much of the gruesome details, I have killed it with the good old method. However, I still have been bitten by its reflex. Next time I know even if its claw detached from its body, it still can bite and it's painful... ouch!!!
