The late-night comedy wars appear to be heating up.
Andres du Bouchet, a writer for TBS’ Conan, took to Twitter on Thursday (April 16) to criticize the TV comedy landscape in a series of scathing messages.

“Comedy in 2015 needs a severe mother-f—ing shakeup. No celebrities, no parodies, no pranks, no mash-ups or hashtag wars,” he wrote before adding: “And shove your lip-syncing up your ass.”

“Prom King Comedy,” du Bouchet continued. “That’s what I call all this shit. You’ve let the popular kids appropriate the very art form that helped you deal. F—.”
In one tweet featuring a string of expletives, he asked how to block hashtag wars from his feed, a reference to a hallmark of shows like @midnight, with viewers encouraged to tweet their suggestion in a comedic category.

A day later, du Bouchet tweeted that he was a “bonehead” for the rant, writing: “Now comes the inevitable dressing down at work for criticizing other talk shows!” He also pointed out that he was looking forward to seeing Stephen Colbert on CBS’ Late Show.
Du Bouchet did not name any other shows specifically, but the Tonight Show With Jimmy Fallon is known for its lip-sync segment, with other shows trying their hand at it, while Jimmy Kimmel Live is famous for pranks. Parodies and celebrity-centric bits have become late-night staples as well, notably with Fallon playing games with his guests or reuniting the Saved by the Bell cast.
The late-night genre is currently undergoing major upheaval, with the impending departures of David Letterman and Jon Stewart and the recent arrival of James Corden’s Late Late Show. Conan O’Brien himself was at the center of one of the nastier late-night flaps in recent years, as NBC took the Tonight Show away from him in 2010 after only eight months at the helm.
