Da Ali G Show
Sacha Baron Cohen's ambush-interview show, and the launchpad for three of comedy's most infamous characters. Beginning on Britain's Channel 4 in 2000 and crossing to HBO in 2003, it sent Cohen — in character as faux-streetwise poseur Ali G, Kazakh reporter Borat, or Austrian fashionista Brüno — into real interviews with unsuspecting politicians, celebrities, and experts who had no idea they were being had. The results were excruciating, brilliant, and eventually spun off into a string of hit films.
