This is not the first Centiburger. Last year, on the same date, I held the first Centiburger. This event involved only 103 burgers and did not raise any money, though it did raise a few eyebrows. This event was featured on CollegeHumor.com and a video of the event can be found on Google Video.
The following are some pictures of the event:
Here's a picture of the two receipts. They could only fit 99 cheeseburgers on a single receipt, so they put four on the other receipt. These four were somehow put down as double cheeseburgers. Notice the phantomburger that snuck its way onto the first receipt.
