Jury Duty: How many times can you be called?

[mooby]

My dad never got called for jury duty once in the last 24 years up until last July, when he got called to do local jury duty every Tuesday for a month. He had to go 3 out of 4 possible Tuesdays. And he just got another letter informing him he's been selected for jury duty in a federal court in Alexandria starting next month, only he's going to have to take a lot more time off because jury duty in federal court is apparantly a lot more time consuming. I hope I never get called for that shit, I mean it sounds like you never know when your bell is going to get called. If I didn't know any better I'd say they keep pulling your name up simply because on the day you're supposed to go you're not needed, so they'll keep calling you up until you are needed.
