            my mama said
            that your life is a gift
            and my mama said
            there's much weight you will lift
            and my mama said
            leave those bad boys alone
            and my mama said
            be home before the dawn
            and my mama said
            you can be rich or poor
            but my mama said
            you can be big or small

            and my mama said

            baby don't ride that crazy horse
            and my mama said
            you must push with much force
            and my mama said
            go get all that you're after
