Zev Sero               All around myself I will wave the green willow
zev at sero.name          The myrtle and the palm and the citron for a week
                And if anyone should ask me the reason why I'm doing that
                I'll say "It's a Jewish thing; if you have a few minutes
                I'll explain it to you".
