I thought "carrot and the stick" meant laying a carrot out on the ground in front of the horse (which it'd walk towards) and laying a stick on the ground behind the horse (which it'd walk away from because it would hurt stepping on the stick.)
And I wondered, why would stepping on a stick hurt a horse?
