Gareth Keenan is the humorless Assistant Regional Manager at Wernham-Hogg, meaningless role as "Team Leader," and attempts unsuccessfully to assert imagined authority over his co-workers. Obsessed with his service in the Territorial Army, Gareth constantly brags about his supposed military skills: "I could catch a monkey. If I was starving I could. I'd make poison darts out of the poison of the deadly frogs. One milligram of that poison can kill a monkey. Or a man. Prick yourself and you'd be dead within a day. Or longer. Different frogs, different times." (Work Experience) Gareth's ignorance and overblown self-importance make him a target for practical jokes; his office nemesis, Tim Canterbury, plays endless pranks on him for fun. Gareth claims to be a great Casanova, but his frequent attempts to woo female co-workers are generally unsuccessful (although he has had some successes in Chasers). He ultimately becomes a regional manager following David Brent's departure from the branch in the Series Two Finale.
