She is as thin as a rail.

The fireplace kept the room warm as toast.

It's as hot as Hades outside.

He was as happy as a sandboy.

Her house is always as neat as a new pin.

A change is as good as a rest.

Her room is always as neat as a pin.

He was mad as a bear with a sore head when he found out his car had been towed.

The desert was as dry as a dead dingo's donga.

He is as dumb as a doornail.
