Ali G

Ali G is a satirical fictional character created and performed by English comedian Sacha Baron Cohen. Originally appearing on Channel 4's The 11 O'Clock Show, and subsequently as the title character of Channel 4's Da Ali G Show in 2000 and on HBO in 2003–2004, he is also the title character of the film Ali G Indahouse. In December 2007, in an interview with The Daily Telegraph, Baron Cohen announced that Ali G, along with Borat, had been retired. However, Ali G returned at the 2012 British Comedy Awards to accept Baron Cohen's Outstanding Achievement Award, causing controversy by making jokes about Kate Middleton and Jimmy Savile.
