giant tomato plants

Here is a picture of me atlast..... standing next to my monstrously tall tomato plants. They are taller than I am. I think I am missing a step in growing them.. One plant has about 15 tomatos, the other only 3. I seriously have no idea why they are so giant. I have not fertilized then at all.

I decided to not show the picture from feet up cause my diet dr pepper belly wasn't properly sucked in. ( I have no idea why my words were underlined.. and no idea how to make them not underlined )
