Don’t worry, I’m not recommending fist fights in your Sukkah (the temporary hut Jews inhabit during the festival of Sukkot). That would likely wreck the walls of your Kosher Sukkah!
I’m simply noting that one of the main themes of the Fight Club, a thought-provoking movie starring Brad Pitt and Edward Norton, is also a dominant theme of Sukkot. This theme has much to teach us about simcha (Jewish joy).
