Had to laugh because a very good friend, who happens to be Jewish, used to throw smoked fish into swimming pools of people who upset her. (Another friend, not Jewish, emptied a small bottle of pickled herring into the overcoat pocket of a man who annoyed him.)

You need to find a better class of "friend," Arik. You're describing immature and petty valley girl and frat boy behavior. How unfortunate for you that you find it "funny."
