Robert Kaseberg says his jokes about Tom Brady, Caitlyn Jenner, airlines and the Washington Monument made it into the late night host's monologue.
A San Diego man has filed a lawsuit against Conan O'Brien, TBS and others on the comedian's team for allegedly violating copyright on four jokes.
According to a complaint filed on July 22 in California federal court by Robert "Alex" Kaseberg, the jokes were posted on a personal blog and on Twitter before making it into O'Brien's late night show monologue.
Kaseberg, who says he contributed to The Tonight Show with Jay Leno for 20 years, states in the lawsuit he published the first joke in January 14, writing, "A Delta flight this week took off from Cleveland to New York with just two passengers. And they fought over control of the armrest the entire flight."
That same day, O'Brien made a similar joke on his show.
One of the other jokes dealt with Tom Brady and the other with Caitlyn Jenner. The fourth joke was about the Washington Monument.
"The Washington Monument is ten inches shorter than previously thought," Kaseberg tweeted. "You know the winter has been cold when a monument suffers from shrinkage."
This allegedly formed the basis for Conan's own joke.
