None Pizza with Left Beef was a pizza delivery experiment by Steven Molaro in October 2007. After testing the accuracy of Domino's' then-new online ordering system, the humorous results were posted on his blog, The Sneeze, after which it evolved into an internet meme.
Background
On October 18, 2007, Steven Molaro was experimenting with Domino's' pizza-ordering website, specifically testing the accuracy of ordering pizza toppings on the "left" versus "right", as seen when opening the box. Using the site's radio buttons, he ordered two pizzas.
The first, with pepperoni on the left and mushrooms on the right, arrived correctly partitioned, though reversed from the specific left–right orientation he had ordered. The second was a six-inch (150 mm) pizza with no sauce, no cheese, and beef only on the left side of the pizza; while correctly absent of the typical base elements, Molaro said, "the whole pizza was so small and light it must have shifted during delivery. And the little beef pellets didn't have any sauce or cheese to hang on to, so a few lost their footing from the left half."
