You Harlot

Margot Asquith, wife of the British Prime Minister Lord Herbert Henry Asquith, was known for her biting wit.

When she and movie star Jean Harlow met for the first time, Harlow was careless enough to address the lady by her first name. To make matters worse, Harlow pronounced the name as though it rhymed with "lot".

Lady Asquith drew herself up and proceeded to correct Harlow by saying "My dear, the 't' is silent, as in 'Harlow' "
