What is the best way to paint your skin green?

without it coming off on clothes or furniture.... think The Incredible Hulk green. Is there a body paint or powder paint that dries and does not rub off?|||What about trying food colouring .Think you would need quite a few bottles though to cover your whole body.|||First of all Consider yourself Irish...Next rub a pot of gold...a little guy will pop out by rainbow of gold and spray you green. Enjoy it will not rub off
