A Policeman:

What's the trouble here?

The Showman:

A redcoat dog, in need of a thick ear.

The Policeman:

The show turned back? No, sergeant, let them through.
They can't turn back, because the Prince is due.
Best let them pass.

The Sergeant:

Then pass; and read the rules
Another time.

The Showman:

You fat, red-coated fools.
