I'd probably do what Richard did and decline if I was allowed. Juries convene way too early for me.

I once got a preliminary inquiry about being put into a grand jury pool, I think. At the time I was having some very weird issues with hydration and tachycardia and drinking an incredible amount of water, with the expected results. (The issue turned out to be additive medication side effects, but it took quite some time for anybody to work that out.) I described this situation on the questionnaire with, I am afraid, a certain malicious glee. I was not notified that I had been excuse or whatever, but I never heard any more about it.
