In the old country, one Jew's business was to shlepp other Jews from one town to another in his rickety cart pulled by his old horse. One day, a customer paid him his koppeks and climbed into the cart as the old man walked along leading the horse. They rode a very short distance until they came to a hill. The customer agreed, climbed out and walked alongside the man as they climbed the hill.
Exercise is good.
And so it went the entire journey. I know why I was here. I needed a ride. I know why you were here. Its your business.
