Shaking the lulav counts as an Talmudic ritual. The equivalent Islamic ritual involves getting your willy out and shaking it all about, while simultaneously keeping a firm grip on your b0ll0cks with your free hand.
The most fervent amongst them might well also sing as they do this: “Hail, the conquering hero comes”. It’s all part of a great annual spectacle copied from the Jews’ lulav/etrog thing.
