Total

Practise what you preach
Poverty is not a shame, but the being ashamed of it is
Poverty is no sin
Politeness costs little (nothing), but yields much
Plenty is no plague
Pleasure has a sting in its tail
Penny-wise and pound-foolish
Patience is a plaster for all sores
Packed like herrings
Out of the frying-pan into the fire
Out of sight, out of mind
Opportunity makes the thief
Opinions differ
Open not your door when the devil knocks
One today is worth two tomorrow
One scabby sheep will mar a whole flock
One man, no man
One man's meat is another man's poison
One link broken, the whole chain is broken
One lie makes many
One law for the rich, and another for the poor
One good turn deserves another
One fire drives out another
One chick keeps a hen busy
One beats the bush, and another catches the bird
