In March 2014, Chelsea Handler slammed Piers Morgan during an appearance on his show. She called him out for tweeting during the commercial break, saying "You can't even pay attention for 60 seconds. You're a terrible interviewer.” When Mogan replied that he had been bored, she replied, “You signed up for this job. Maybe that's why your job is coming to an end." Brutal.
