I've been called 4 times, but only selected for a jury once. It was a civil case for someone who slipped on a wet floor at a grocery store.
It was kind of fun, as we got to be part of a "test" trial, where the trial was limited to 4 days, and then the jury got to deliberate, and then come back and ask questions of any witness in the case.
Since I was selected foreman, I got to ask the questions, which was kind of cool.
The store had admitted liability, but they couldn't come to an agreement on the amount. We ended up giving him less than he had been offered in a settlement (which we did not know at the time of the decision).
It was nice to do this once, but I wouldn't want to do it again, especially on a criminal trial.
For those who don't know what "Streak for the Cash" is, it's a game on ESPN.com. You pick winners. Sometimes it isn't a straight-up pick of a game, but Player A vs. Player B - who will score more points-type of things.
