I second the just do it! answer. In the northern counties they have it so streamlined you frequently only have to go for one day, if at all, so it's almost impossible to get out of it (picture the assingnment judge asking "you don't have ONE DAY to spare for your civic duty?)

EDIT: imacarnut responded while I was typing...I was going to say, that it's easier to get out of a specific jury (like if it's expected to be a long trial) than to try and get out of the pool.
