Revenge of the Cockroach

I whacked a cockroach in the kitchen couple of weeks back. The poor thing was dead before you can say "AH!". It wasn't even struggling when I scooped it out. Merciful me gave it a quick, albeit painful death.
Today, while watching soccer at this seaside pub, something dropped on my head. ON MY HEAD! I brushed it away nonchalantly, only to find that it had dropped on my shirt. It was only then, that I realised it was Xiao Qiang's cousin, Da Qiang. It would be embarrassing to whack it in front of so many people, so I let it drop and it scurried away. Operation "To scare Marcus", planned by Da Qiang failed. I'm sorry. I wasn't ready to get frightened in public. Maybe if you tried again now, I might jump out of my seat and gas the entire room.
