A bad penny always turns up.
A barking dog never bites.
A bird in the hand is worth two in the bush.
A chain is only as strong as its weakest link.
A dog is a man’s best friend.
A fool and his money are soon parted.
A foolish consistency is the hobgoblin of little minds.
A friend in need is a friend indeed.
A good beginning makes a good ending.
Any mention of pith even pithily must be considered.
M. Pithy Bailey
