Not a day goes by on the internet without someone trying to come up with a new way to outsmart a computer. The Australian friends in the video above found a way to trick the McDonald's self-service machine into giving them 11 free burgers (well, one free burger and 10 pattyless burgers, at least). Don't try this one at home, folks.

The guys talked through what they were doing as they filmed the self-service screen. Here's how they did it...

First, they selected the dollar hamburger option on the menu and requested 10 of them.

"We'll have ten of these and we'll customise them so we don't want a regular beef patty so that takes $1.10 off our order, off our dollar hamburger," said a voice behind the camera.

They then added one regular hamburger to the order.

"10 pattyless burgers, one regular hamburger, oh we get our discounts, that's pretty good," the voice continues.

"When it gets to this screen, you'll find that all the pattyless burgers have $1.10 taken off them so they're all -$.10 and there's a regular burger which is just a buck, leaving the total at $0," he adds.

Mashable has reached out to McDonald's and we will update this article once we've received a response.
