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

On the flip side

Pull the other one, it’s got brass bells on

Pull rank

Practise what you preach

Pound of flesh

Polishing peanuts

Poacher turned gamekeeper

Play hard to get

People who live in glass houses should not throw stones

Peeping Tom

Pass the time of day

Out of your hair

Other side of the coin

Other fish to fry

One-trick pony

One man’s trash is another man’s treasure

One man’s meat is another man’s poison

One man’s loss is another man’s gain

One hand washes the other

One good turn deserves another

Pull the other one, it’s got brass bells on

Pull rank

Practise what you preach

Pound of flesh

Polishing peanuts

Poacher turned gamekeeper

Play hard to get

People who live in glass houses should not throw stones

Peeping Tom

Pass the time of day

Out of your hair

Other side of the coin

Other fish to fry
