Last time I was called, I reported the first day but was among the bunch released when it was realized they'd called way more than were needed for the session. However, in 1985 I sat as an alternate jurer on a murder trial that was fairly notorious. The crime had been committed 20 years earlier, the victim (a young lady) had been good friends with the state's lieutenant governor, and an airman from the nearby base tried and acquitted soon after the murder. At the time, I was relieved that no jurers had to be excused, but in hindsight wish I'd been in on the deliberations. The guilty verdict came back in just under two hours.
A few years before that, I was a defendant's witness in an adverse possession (squatter) claim in the north woods. Plaintiff's attorney grilled me for at least two hours, and when the judge asked our attorney if there were any questions, the reply of, "No, your honor" was about the nicest response possible. The judge ruled that claim of ownership had come only two years before the hearing (our state requires 20 for such a claim, also that occupation be "continuous, notorious, and hostile"), and dismissed the claim. The landowners for whom I worked as a forester then offered plaintiff a lease; they didn't want to kick the man off, just to have it be clear who actually owned the land. Unfortunately, the fellow never paid the lease fee, something like $100/year for a camp on a large stream 1/4 mile from a designated Wild and Scenic River, and so after several years lost it.
