Don Gorske says he's eaten 23,000 Big Macs in 36 years.
The Wisconsin prison employee says he has every burger receipt to prove it.
Gorske's Big Mac obsession began in May of 1972 when he got his first car.
He's eaten a Big Mac every day since, except on the day his mother died.
Gorske knows lots of people will think he's a few mental ounces short of a Quarter Pounder.
But he doesn't care.
He says Big Macs are the best part of his day.
