Conan O'Brien took to Twitter on Sunday afternoon, and let's just say somebody might want to think about calling in sick to work on Monday morning, because it's gonna be a little bit awkward at the office. 

A day after Conan writer Andres du Bouchet took to Twitter to release his thoughts on the state of crappy late night comedy shows, pretty obviously aiming at the Tonight Show With Jimmy Fallon, his boss posted a tweet, pretty obviously aimed at him. 

Burn. 

In a string of since-deleted tweets (which you can still see here) du Bouchet referred to shows like Fallon's as "prom king comedy," and said what late night TV needs is "no celebrities, no parodies, no pranks, no mash-ups or hashtag wars," before he told nobody specifically  to "shove your lip-synching up your ass."

After Conan's tweet, du Bouchet seemed ready to put the whole thing behind him with jokes about a cult classic/worst movie ever made.
