many years ago (20+) I was called up for jury duty but my Physio wrote a letter saying I had chronic back pain & couldn't sit unmoving for long periods. I got exempted with a Standard Reply saying if my condition cleared/healed (or words to that effect) I could be called up again!

I worked in a secure Federal Govt agency - staff were limited where they could go. Once in a fire drill I heard a bloke ask another was he still in a particular section, No, he had moved to another 2 years before, & I once saw a colleague I hadn't seen for a long time. Turned out she had been a juror in a 12 month trial ...
