Big Mac Attacker

A 54-year-old Fond du Lac, Wis., man says his obsessive-compulsive disorder drove him to eat 23,000 Big Macs in 36 years.

Don Gorske, 54, says he hit the milestone last month, continuing a pleasurable obsession that began May 17, 1972 after he got his first car.

So how did Gorske keep a tally of the Big Macs? He kept every receipt in a box. He says he was always fascinated with numbers, and watching McDonald's track its number of customers motivated him to track his own consumption.

The only day he skipped a Big Mac was the day his mother died, to respect her request.
