Don’t throw bricks when you live in a glass house

Put some mustard on it!

Put on airs

Put all your eggs in one basket

Pull your weight

Pull your punches

Pull rank

Pull out all the stops

Press the flesh

Presence of mind

Practical joke

Pot calling the kettle black

Politically correct

Pointy-heads

Playing to the gallery

Play hardball

Play hard to get

Plastic smile

Plan B

Pig in a poke

Piece of cake

Photo finish

Perish the thought

Penny wise, pound foolish

Paper tiger

Pandora’s box

Over-egg the pudding

Out of your own pocket

Out like a light

Other side of the coin

Opportunity knocks but once

Open old sores

Open all hours

One-man band

One swallow does not make a summer
