Now, to a university that's turning out some of the world's top hamburger experts.
You might not have heard of the Ohio [Illinois] campus, but you'll recognize its logo in a flash.
CNNMoney reporter Poppy Harlow gives us an exclusive look
at the crash course which has been producing Big Mac management professionals for more than half a century.
Well, from Shanghai to Brazil to Chicago, more than a quarter million people have graduated from McDonald's Hamburger University.
It is McDonald's training ground for their high-potential employees, and they graduate with a degree in hamburgerology, as you can see.
We took a visit for ourselves.
McDonald's serves 60 million people a day, but here at Hamburger U, students don't learn how to flip burgers.
The food is actually fake.
These students are learning the management skills to make a restaurant hum in a five-day course,
grooming them to be owners.
In the first simulation, long lines, frustrated customers and flustered managers,
then the orders get more complicated, designed to test the limits of the operation.
How do you think this is impacting your customers?
Everybody is getting upset. All you see is the manager running back and forth and not really helping.
It's more chaotic than anything else.
So, back to class.
All right, my teams. Should we talk about what just happened?
They were friendly. I just wasn't getting my food very quickly.
It was just really busy. It kept holding, so she kept sending everybody on break.
So they try again, this time, applying the lessons of the classroom to cut the chaos in the kitchen.
Okay, here we go.
Hi, would you like to try an iced mocha today?
I would like cinnamon melts; a bacon, egg and cheese bagel; a sausage egg McMuffin, and a hash brown.
I'm just really in a rush.
Pretty fast so far. Let's see if they get the order right.
We have a bacon, egg and cheese bagel; we have a cinnamon melt and we have one hashbrown.
And what about the sausage McMuffin?
Sausage egg muffin?
C'mon, guys. They said it was in a rush. Let's go.
And I got it for you.
That was a minute and 30 seconds.
And Hamburger University isn't a new thing.
It was founded all the way back in 1961 in the basement of an Ohio [Illinois] McDonald's with just 14 people,
as I said, about a quarter of a million have graduated since then.
And this is no joke, McDonald's says Hamburger University is the key to its success over the years.
Major companies like Target and Wal-Mart have sent their executives in to see just how McDonald's trains its employees
and some colleges even give credit to students who attend Hamburger U.
What this shows us is there's a lot more behind those golden arches than we knew before.
