I've gotten the jury duty questionnaire in the mail twice. Once I filled it in and wasn't even picked to come in to sit around on the hard bench. The second time (more recently) I got a date to come in and sit around but was dismissed over the phone the morning of. (If I recall correctly I was supposed to come in on January 2.) Maybe it's just the luck of the draw or maybe one of my questionnaire answers was unattractive to one of the attorneys...
