In 2009, Fox played himself in the comedies "Party Down" and "Head Case", and he currently has recurring roles on VH1's "Single Ladies" and "Tyler Perry's House of Payne". In 2010 Fox briefly guest starred on the science-fiction series "Dollhouse", and took on a recurring role on the CW remake of "Melrose Place". In 2011, Fox then played the role of Bernadette's ex-boyfriend Glenn in "The Big Bang Theory" episode "The Love Car Displacement". In an article about his appearance, "TV Guide" quoted Fox as saying about his role, "It's all in Glenn's head now. 'How am I losing to this guy? He's smarter than me ... I love that they turned the 'threatening ex' on its ear. At the end of the day, I have more insecurity about my intellect and am constantly fighting to be accepted intellectually and be seen for more than my looks and my size. I want to appear intelligent and prove my intelligence. That's where I'm battling with him."
