In 2008, a TV commercial for a ringtone which featured Dunham's character Achmed the Dead Terrorist (see Characters below) was banned by the South African Advertising Standards Authority after a complaint was filed by a citizen stating that the ad was offensive to Muslims, and portrayed all Muslims as terrorists. Dunham responded that "Achmed makes it clear in my act that he is not Muslim." However, the ASA noted that the name Achmed was of Arab origin and was one of the names of Muhammad. Dunham responded, "I've skewered whites, blacks, Hispanics, Christians, Jews, Muslims, gays, straights, rednecks, addicts, the elderly, and my wife. As a standup comic, it is my job to make the majority of people laugh, and I believe that comedy is the last true form of free speech ... I'm considering renaming Achmed 'Bill'", he added. Dunham has conceded that he does exhibit particular sensitivity to the "conservative country crowd," or those characterized by "basic Christian values", as they are one of his largest constituencies, and part of his upbringing.
