Just one pig

Big man, pig man, ha ha, charade you are
You well heeled big wheel, ha ha, charade you are
And when your hand is on your heart
You're nearly a good laugh
Almost a joker
With your head down in the pig bin
Saying "keep on digging"
Pig stain on your fat chin
What do you hope to find?
When you're down in the pig mine
You're nearly a laugh
You're nearly a laugh
But you're really a cry.
