Tidbits from #JuryDuty orientation:

You can use the bathroom even during the orientation. You won't miss anything because there are speakers in there.

You can get a letter verifying your service for your employer or *spouse*. "Jury duty my ass, Harold, you were out with that floozy again!"

Apparently there's a problem with jurors telling the judge (of whom they're afraid), "Yes, I can serve that long," then coming back to the waiting room and stage-whispering to a clerk, "not really".
