I absolutely love McDonald's hamburgers. McDonald's was founded in 1940 by Richard and Maurice McDonald, you know?
I saw that movie about early McDonald's
Americans take credit for the invention of the hamburger. They say that we were the first to put a steak of ground beef between two slices of bread.
Interesting!    Buns came later?
At first it could be placed between halves of a sliced bun, between slices of bread, or even toast.
Wow!  What about cheese?
It is true that McDonald's is known for their cheeseburgers, chicken, french fries, breakfast items, and more. I like cheeseburgers too.
