Howard loves to pull out his monster side from time to time. He has a history of telling people they are worthless and could go at any time. He pulled that on Stuttering John over and over. He tried it on Fred once and Fred walked out... someone had to run after him. He tried it on Gary more than once and Gary nearly walked once or twice. His treatment of Riley is wonderfully dispicable. There is nothing more humiliating than getting fired by someone you look down upon. Thus, Howard gave JD the power to dump Ronnie's show. JD recognized that Howard loves it - for the sake of the show - when staff members tattle on one another or show disrespect to one another. Thus, in reality Howard dumped Ronnie when he gave JD rather than Tim the right to dump the show. The result was inevitable. No one has the guts to tell Howard he is responsible...
