Question mark

The question mark is a piece of punctuation used by many languages on Earth, usually denoting an inquisitive sentence and, by itself, representing an unanswered, unasked question.

During his sixth and [[Seventh Doctor|seventh][ incarnations, the Doctor adopted the question mark as something of a personal motif:


 * The sixth incarnation displayed it on the lapels of his shirt.
 * The seventh incarnation wore a jumper covered with the symbol, carried an umbrella with a handle shaped like a question mark, carried a business card with a stylized question mark, and when asked to sign his name, did so with a question mark (DW: Remembrance of the Daleks).
