Let he who is without brains cast the first
stone (contributed by Mat)
A war broke out between two neighbouring
countries - a small island and
its northern neighbour. The southern,
predominantly Chinese soldiers decided to
pull a trick on its northern enemy.
The southern troops called out "Eh, Mat!
Mat!", and suddenly the northern troops began
standing up and asking "Siapa
panggil aku?" (who's calling me?).
The southeners immediately opened fire, killing a great number of
these mats.
Furious, the remaining Mat soldiers decided to pull the same trick
on their enemies... "Oi, Lee! Lee!", they shouted, and the
Lee Soldiers started shouting back, "Kong simi?" (What are you
talking about?).
The mat soldiers immediately stood up and replied, "Aku lah!" (Me,
lah!), getting their
heads shot off soon after.
