Carlos Mencia isn’t the most popular comedian amongst his fellow comedians. He’s been highly criticized to the point of being called one of the top twenty worst comedians of all time. Joe Rogan posted on his website in 2005 that Mencia had plagiarized and stolen several jokes from a number of comedians. The accusations continued in 2007 when Rogan confronted Mencia about it and recorded the whole thing. He placed the video and audio clips online with video clips from other comedians including George Lopez and Ari Shaffir.
Rogan also posted clips of Mencia’s jokes compared to other comedians on his blog. Mencia got in a physical altercation with George Lopez over allegedly stealing one of his jokes. He’s also been accused of stealing jokes from Bill Cosby. The whole plagiarism situation was played out in an episode of South Park that ended in Mencia admitting he wasn’t funny and being killed by Kanye West. Mencia admitted in 2011 that he started going to therapy over the allegations of his plagiarism.
