"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 gaunt, 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 steadfast enforcement of the rules and sucking up to boss David Brent, whom he views as a mate."@en . "Gareth Keenan"@en . .
