He has a star on the Hollywood Walk of Fame and holds the Guinness Book of World Records record for "Most tickets sold for a stand-up comedy tour" for his Spark of Insanity tour. Dunham has been called "America's favorite comedian" by Slate. His introduction of Achmed the Dead Terrorist in Spark of Insanity in 2007 was ranked as the ninth most watched YouTube video at the time while his A Very Special Christmas Special was the most-watched telecast in Comedy Central history, with the DVD selling over 400,000 copies in its first two weeks. Forbes ranked Dunham as the third highest-paid comedian in the United States behind Jerry Seinfeld and Chris Rock and reported that he was one of the highest-earning comics from June 2008 to June 2009, earning approximately $30 million during that period. His style has been described as "a dressed-down, more digestible version of Don Rickles with multiple personality disorder". Time described his characters as "politically incorrect, gratuitously insulting and ill-tempered." Dunham has been credited with reviving ventriloquism.
