The oyster and the pig

Ta dida da,
Said the oyster to the pig.
Ta dida da,
You're getting, ahhh... To be precise,
You're getting quite big.
Ta dida da,
The oyster was told by the pig,
I'll fetch a handsome price.
Think I ought to wear a wig,
Or would that be like gambling with a pair of weighted dice?
Ta dida da,
Yo dida dae,
That's what I saw,
The oyster to the pig say.
