Tuesday

Tuesday was a day of the week.

Opinions
According to the Fourth Doctor, "Nobody does anything of importance on a Tuesday." (PROSE: The English Way of Death) The Eleventh Doctor, similarly, listed Tuesdays in his list of "boring stuff", along with Sundays and Thursday afternoons. (TV: The Impossible Astronaut) When the Fourth Doctor informed his other incarnations that the Earth was facing "the greatest peril in its history", the Fifth Doctor asked if it was Tuesday, to which the Seventh Doctor concurred that it "sound[ed] like a Tuesday". (WC: Doctors Assemble!)
