In 2008, she became the first Briton to perform on "Def Comedy Jam". On 3 September 2009, she appeared on "The Tonight Show with Conan O'Brien" and performed a stand-up comedy routine. On 24 December, she appeared on "Live at the Apollo". She appeared twice on the short-lived primetime show "The Jay Leno Show": on 21 October 2009, a video of Yashere showed her giving free fortune-telling readings to passers-by, and on 25 November 2009, she operated a walk-in psychic booth. Since 2010, she has appeared semi-regularly on "The Tonight Show with Jay Leno", in a sketch comedy series called "Madame Yashere: The Surly Psychic". In the sketches, she continues to give fake psychic readings to unsuspecting people on the street.
