I didn't know..

Was telling yw that the beginning of the song "Dongle" from Tank sound like "Zhui" of Leslie Cheung.

Then she told me something that I never knew.

"ABC", "Twinkle Twinkle Star" and "Blah Blah Black Sheep" (All don't know if correct song title) are of the same tune. I seriously didn't realise that!!

So now I learnt something new.
