Has anyone watched the show Documental? It's a show where a bunch of comedians try to get each other to laugh, and if you laugh you're eliminated. What happens at the end of that show is that they start becoming desperate. It's no longer about trying to be funny, and instead turns into just spreading your asshole and pissing on the floor and acting like a lunatic, because they have exhausted all their usual tricks to make people laugh.
I felt that this was what happened to Sam during this podcast. He tried so hard to be the funny puppet master, trying offend Harland with racist remarks, tried to be shocking, insulting his set, insulting his style of comedy, etc. But nothing was hitting, and Harland was quick at jabbing back at him every single time, making his crew laugh. So running out of options, knowing he was looking like an unfunny asshole, he got desperate. And not only did he tip over his desk, sending camera and audio equipment crashing towards the floor, he started physically assaulting him, but not even that had any effect on Harland. Harland effortlessly beat Sam at his own game, showing what a real comedian can do, instead of surrounding himself with ego stroking wiggers.
This is honestly the biggest comedian crash-out i've seen since Michael Richard yelled nigger at the Laugh Factory.
