Powder your nose

Pink slip

Over my dead body

Out-and-out

Powder your nose

Pink slip

Over my dead body

Out-and-out

On a silver platter

New man

More holes than Swiss cheese

Memory like a sieve

Man of letters

Like a beached whale

Letter of the law

Let’s call it a day

Let your hair down

Let your guard down

Let the grass grow round your feet

Let the genie out of the bottle

Let the devil take the hindmost

Let the chips fall where they may

Let the cat out of the bag

Let the best be the enemy of the good

Let sleeping dogs lie

Let bygones be bygones

Let alone

Knock the pins from under someone

Keep your pecker up

Hear a pin drop

Have a crack

Go the whole hog

Go spare

Go off on a tangent

Give a big hand
