• At Dayeinu, Persian and Afghani Jews hit each other over the heads and shoulders with scallions every time they say Dayeinu! This really keeps the children alert! They especially use the scallions in the ninth stanza which mentions the manna in the desert, because Torah tells us that the Israelites began to complain about the manna, and longed for the onions, leeks, melons, and garlic in Egypt. 
  • Yemenite Jews lift the table and bang it down at every Dayeinu!
