An Idiom a Day Keeps your English Awake!

Like Two Peas in a Pod

An Arm and a Leg

Neck and Neck

Kick the Bucket

Hit the Sack

Couch Potato 

Best Thing since Sliced Bread

That’s the Way the Cookie Crumbles

Let the Cat out of the Bag

Between the Devil and the Deep Blue Sea 

Two Heads are Better than one … but two many Cooks Spoil the Broth

A Hard Nut to Crack

Pull Somebody’s Leg

The Early Bird Catches the Worm

To be a Piece of Cake

Birds of a Feather, Flock Together

To Have a Skeleton in the Closet

Butterfingers

Set in Stone

Don’t Count your Chickens before they Hatch
