There is an old Peruvian saying, "A person who represents himself has a fool for a client." The man in this video obviously did not take that saying to heart. I do not know the back story on this, but after watching the video I think I can figure out.
A man commits some type of crime, and decides not to spend the money on a lawyer but rather to invest that money in acting class and a new suit. He also manages to tell one of the witnesses that he has a plan to cause a mis-trial. When the time comes to cross examine a witness he decides it is time to show the ace up his sleeve. He asks the judge to excuse his behavior he just needs a second. When the judge doesn't respond he repeats it, then starts his acting. He fakes a heart attack and collapses on the floor. (Side note, if this is not the first time you have watched the video, watch the guy on the far right side, he has no reaction when the man falls over.)
You have to give this guy credit though, even though he is called out by the judge as a faker he sticks with it, acting like he is passed out the whole time. Enjoy.
