“…and not in the towel.”
The line is from Jean Aouilh and Peter Glenville‘s Becket, during a scene in King Henry II’s bathinq auarters. Becket (Richard Burton) is vigorously drying Henry (Peter O’Toole) with a towel, and the king says, “I made you a nobleman — why do you play at being my valet?” Becket’s reply is that dignity comes from how well a person performs a given task, not so much from the status of the task itself.
