Enligt Empire Magazine skrev Steven Moffat de 11: e läkarnas första ord.
Chris Chibnall will write the first words for Peter Capaldi's replacement in the 'Doctor Who' Christmas special.
The 46-year-old television writer will take over from current showrunner Steven Moffat on the popular BBC One sci-fi drama after this year's annual holiday episode, which will also mark the last outing for actor Peter Capaldi, who portrays the titular regenerating Time Lord.
But although Chris doesn't take over the position until after the Christmas special, 55-year-old Steven has given him the honour of penning the first piece of dialogue to be spoken by Peter's yet-to-be-cast replacement.
Steven told Empire magazine: "I haven't completely planned it, but I quite like the insanity of the fact this is a job you quit two pages before you type 'End Titles.'"
The decision emulates the one made by previous showrunner Russell T Davies when he stepped down from the role in 2010, as he let Steven pen the first words to be spoken by Peter's predecessor Matt Smith, who took over from David Tennant.
Det här utesluter naturligtvis inte möjligheten att Davies, Smith eller någon annan föreslog ordet "Geronimo", men jag tror att antagandet borde vara att det var Moffat.
