"Oh, my giddy aunt" was a colloquialism that was often used as an exclamation of surprise.

By the DoctorEdit

The Second Doctor used the phrase often. He said it to himself when surprised by a Kroton, (TV: The Krotons) to Sergeant Benton as a Gell guard tried to enter the TARDIS, (TV: The Three Doctors) and to Dastari during an argument in a cellar. (TV: The Two Doctors)

A clone of the Second Doctor said it as Lucius threatened to devour him. (AUDIO: Survivors in Space)

The Eleventh Doctor said it while facing a Diceman with Henry Gordon Jago. (AUDIO: The Jago & Litefoot Revival)

The Seventh Doctor, when asked about his family, once listed only his granddaughter and a giddy aunt, "but she was probably a metaphor". (AUDIO: Forever Fallen)
