I like chinese,
I like chinese,
They only come up to your knees,
Yet they're always friendly and they're ready to please.

I like chinese,
I like chinese,
There's nine hundred million of them in the world today,
You'd better learn to love them, that's what I say.

I like chinese,
I like chinese,
They come from a long way overseas,
But they're cute, and they're cuddly, and they're ready to please.
