On the Food network they boil potatoes, but they poach carrots. They poach turkey, but they boil eggs. They sauté' onions, but they fry eggs in the same pan. Likewise, they fry hash browns, but they sauté' onions in the same pan before adding the potatoes.
I can go on for days.
I looked it up and cooking oil definitely can boil in a physics/chemistry sense of the word. That temp is well above the smoke point. I agree that in a practical sense boiling oil is a fire ball before you'd ever have to worry about breathing too much oil vapor though.
