It has been raining cats and dogs.

To beggars description

The parliamentary inquiry into the Bofors deal has not <u><em>brought to light</em></u> any star…

To snap one's fingers

To mind one's P's and Q's

He is a <u><em>person after my own heart</em></u>.

In double-quick time

To set the people by ears

One should not indulge in <u><em>tall talks</em></u>.
