In all seriousness, scholarships if you can get them and federal loans are probably the best way to go if you and your family can't pay. They are good because unlike normal loans you don't have to start paying anything back until you graduate, and even then you don't have to for a while (though this will mean you'll pay more in the long run). Once you're a doctor, paying back loans won't be a problem. The problem will be how long it takes to pay them back.
I worked in my gap year and have enough saved up to live off for first year. I am borrowing my first year's tuition from my parents. I'll still have to pay them back the 43k I borrowed, but I won't have to pay the 25-40k in interest that would potentially come with the fed loan.
