Steve throws chairs. This is a major safety concern for everybody on the stage and sometimes in the crowd. What if it hit someone? Would he be doing it then? The sad part is he just might be. Once on an older episode, he threw it directly at someone's head. It just barely missed him. What if it actually did hit him? I'm not defending the guest because he was a big S.O.B., but two wrongs don't make a right. On top of that, he tells his guests (and on rare occasions, the crowd) to "grow up" and to "stop acting like a kid". If he wants childish behavior, he should look in a mirror.
He tells guests to "stop swearing", yet he swears himself (this can be seen on a lot of episodes). He even tells people to shut up! While most of the time the guests deserve it, two wrongs don't make a right. The point is that he does anything himself that he tells his guests not to do.
He brags about being a former police officer. If he wants to help people in bad times, he should still be one.
He offers guests help. If anybody needs help, it should be Steve himself. All Steve does is make himself worse than the guests.
