The rye, the barley, and the oat decided to spend the winter outdoors. The oat became cold all by itself and said, "Let me go home. 1 will bring my daughter. Together we’ll be warmer."
The oat left and didn’t come back. Since it wanted to be a two-some, it so remained and there are always two on a stalk.  When the frost came, the barley became frightened of the cold and, without asking the rye, went home. But the rye saw this, took a stick, and threw it into the barley. And now the barley is always with a stick.
And since the rye stuck to the agreement and stayed the winter, it is clean, without a stick.
