Gareth Keenan (born 17 April 1971) is a fictional paper salesman on BBC's comedy The Office. He is portrayed in the series by Mackenzie Crook as a self-important team leader proud of his alleged Lieutenant status in the Territorial Army. He spends his days annoying his co-workers at Wernham Hogg with his rigid enforcement of the rules and sycophantic attitude towards David Brent, whom he views as a friend. David Brent often has to correct Keenan over his apparent job title "Assistant regional manager" to "Assistant to the regional manager". His counterpart on the US series is Dwight Schrute. The character was originally meant to be a tough and fierce character in the mockumentary, but after Crook's audition, Ricky Gervais and Stephen Merchant had to change his lines to fit his new personality.
