Probably and it also depends on the length, volume and time your laughing session begins. You might just be removed from the courtroom. I have no idea why you consider everything funny in the courtroom. This is serious, maybe not for you, but for the litigants. This is not a joke. there are real ramifications on many court decisions, so try and control yourself. And remember, if YOU are the litigant/defendant, the judge sees your behavior and will gather an opinion of you and that might color how he is going to rule. So, your little outburst might come back and bite you in the butt.
