A little late to respond but I would agree with that. He is a lot more serious than he acts. Plus you got to think these guys are shooting 10-12 hours a day, some times its the middle of the night. I can understand why it's so hard to not laugh at him but it means having to re do takes 5, 10+ times even if the 1st or 2nd was perfect but someone wrecked it by laughing. Also, Michael was playing the hardest character. Jerry is basically playing himself, Julia is not really herself but her character isn't that out there, Jason was playing a crazy character but again none of them where out on the limb like Michael had to do. His character was so out there and he had to make it work. He made people love him despite being mooch and causing a lot of trouble for the other characters.
