Touché
From Tardis Wiki, the free Doctor Who reference
As the Fourth Doctor explained to Leela, "touché" was French for "Ouch, you're very clever." (AUDIO: Energy of the Daleks) The Third Doctor said it to the Master after he threatened to kill Jo Grant were the Doctor not to hand over the dematerialisation circuit for his TARDIS. (TV: Terror of the Autons) The Brigadier said the same to Claire Aldwych when she reminded him that he was being hypocritical in doing just what he criticised her for not long before: looking for evidence to support a premature theory.
