It's a Scottish part -- Macbeth.
They've a' taken Macbeth too seriously that ha' played him.

I'm thinking Shakespeare's ghost maun laugh when it sees hoo all the great folk ha' missed the satire o' the character.

Macbeth was a Scottish comedian like masel'-- that's why I'd like to play him.

And then, I'm awfu' pleased wi' the idea o' his make-up.

He wears great whiskers, and I'm thinkin' they'd be a great improvement to me, wi' the style o' beauty I have.
