Conan O'Brien, who is famously known for being the host of 'Late Night' and the 'Tonight Show and Conan', is facing a lawsuit claiming that the comedian and writer used jokes off Twitter on his show.

Robert Kaseberg from San Diego was shocked when he realised his own personal jokes that he had previously posted on a blog and tweeted on Twitter where in the monologue of the famous host. Mr. Kaseberg filed a complaint on the 22^nd of July in the California federal court claiming that four of his jokes were used by O'Brien during his show which is allegedly violating copyrights.

Conan O'Brien and two members of the  Conan' team which include Executive Producer Jeff Ross and Head writer Mike Sweeney are facing charges for stealing Kasebergs four jokes. Apparently the first joke that was stolen happened way back on January 14 of this year when a Delta Airline Joke that Kaseberg posted was later on heard on O'Briens show the very same night.

Other jokes that were supposedly stolen from Kaseberg happened on the 3^rd of February, the 17^th of February, and the 9^th of June. Each time the joke was either entered into the hosts monologue the same night, or the following day. Kaseberg noted in the lawsuit that he did not receive any money for the jokes nor was he credited for them, because of this he is seeking for over $600,000 in damages.

The Conan television show has voiced their side regarding the issue saying, "We at Conaco firmly believe there is no merit to this lawsuit."

Twitter has finally taken action after many other complaints had been made regarding the same issue. They are currently acting on the copyright complaints and are deleting any word to word theft on their site.
