Careless shepherd make excellent dinner for wolf.

Every man must wear out at least one pair of fools shoes.

This is unexpected... like squirt from aggressive grapefruit.

Do not wave stick when trying to catch dog.

Only very brave mouse makes nest in cat's ear.

But he that is an hireling, and not the shepherd, whose own the sheep are not, seeth the wolf coming, and leaveth the sheep, and fleeth: and the wolf catcheth them, and scattereth the sheep.
