Chinese Master?

i think i'm slowly but surely forgetting whatever little chinese i know. during dinner my dad mentioned some mu4 gua1 drink. i thought for a split second, gave up, and asked,
"wat is mu gua?"

for the benefit of other chinese idiots (if any) out there mu gua is PAPAYA! geez.. it's not that i didn't know that.. learnt tt in pri sch heh. just that at that moment i couldn't be bothered to go and recall it's meaning heh. and my dad's chinese is like.. BAD. he can't read, write or even speak chinese (onli selected words haha). but he knew wat mu gua was and i didn't! oh and i found chinese newspapers in my house just now!!! *stunned*

could my dad actually be a master of chinese in disguise...??
