I really did that, no joke. Me and my former police colleague were walking around Crawford and sitting down for some beer. Two former lockup idiots and imates who were in the know (we actually didn't know how they knew) came up swaggering and said. "You two ah sir, ROD liao, no more warrant card no more gun...hahah..." Pok! My friend suddenly one fist landed square on his mouth and broke his tooth. Actually, my friend's knuckle got cut bleeding by his tooth too.
There was no time to hesitate in such a situation and I immediately followed up by a flying kick on the other guy to ground him follow by a few stomps (not modern internet stomps). Of course, we couldn't go any further than that, otherwise we'd be in trouble even if we know the CP. They strugg;ed, crawled up and said, "Ah sir, you all why like that so serious? Justl joking only lah. Come sit and drink." They went washed up and paid up. We cheered and asked for friendship.
