One funny story is when a juror fell asleep during the trial. The judge noticed and instead of getting angry right away, he loudly said 'I hope the witness's testimony is not too boring for the juror in the third row.' Everyone turned to look and the juror woke up, looking very embarrassed.
There was a jury duty case where the defendant had a really outlandish alibi. A juror during deliberation said in a very serious tone that he believed the alibi because he once had a dream where something similar happened. The rest of the jurors were both baffled and amused at the same time.
One horror story is being on a jury for a really long and complex trial. The evidence was so convoluted and the lawyers were constantly bickering. It felt like we were never going to reach a decision. And the courtroom was stuffy and uncomfortable, making it even more of a nightmare.
I heard of a case where a juror was constantly making puns related to the legal terms being used. It was so distracting but also hilarious. For example, when the lawyer said 'objection', the juror whispered 'I don't have an injection against that'.
One frequent element is being exposed to disturbing evidence. In some criminal trials, the details of the crime can be very graphic and hard to stomach. Also, poor courtroom conditions like bad lighting or uncomfortable seating can contribute to the horror of jury duty.
There was this story I read about a jury duty in a small town. The case was about a property dispute between two neighbors. The jury members were all locals, so they knew the area and the people involved quite well. However, they didn't let their personal relationships influence their decision. They listened carefully to the testimonies and evidence. In the end, they made a decision that maintained the fairness of the law and also helped the two neighbors find a way to resolve their differences amicably.
A juror got really into the trial and started taking copious notes. But instead of writing important facts, they were drawing caricatures of the lawyers and the defendant. When the deliberations started, they accidentally showed their 'notes' to the other jurors. It was hilarious as the drawings were really well - done but completely inappropriate for a jury setting. Everyone had a good chuckle though and then got back to business.
