The leopard does not change his spots.
The only good Indian is a dead Indian.
The shoemaker's children go barefoot.
The work shows the workman.
There is more than one way to kill a cat.
There's many a slip twixt cup and lip.
There's one born every minute.
Those who will not when they may, when they will they shall have nay.
Time works wonders.
To call a spade a spade.
To drop a bucket into an empty well.
To have rats in the attic.
To make the cup run over.
To set the wolf to keep the sheep.
To wash one's dirty linen in public.
True coral needs no painter's brush.
Use it or lose it.
The Dutch have taken Holland !
The fruit does not fall far from the tree.
The longest day has an end.
The opera ain't over till the fat lady sings.
The shoemaker's son always goes barefoot.
The world is one's oyster.
There is no fire without smoke.
There's more than one way to skin a cat.
