21. 'The Office (U.K.)'
Ricky Gervais created one of TV's most agonizing comic tyrants in David Brent – a bitter, awkward, pompous ball of vanities terrorizing his employees at a London paper company. He fidgets, fondles his tie, cracks awful jokes, plays guitar ("Free Love Freeway"!), invisible to anyone except the long-suffering office drones who have to put up with him. This mockumentary raised the cringe level of sitcoms everywhere, spawning the surprisingly great U.S. version (also on this list) while paving the way for the glories of Parks & Recreation and Peep Show.
