Imagine sitting down for a McDonald's Big Mac, then multiplying it thousands of times.
It's Don Gorske's claim to fame.
On Tuesday he will finish off his 25,000th burger.
The Fond du Lac man began his burger quest back in 1972.
He has since eaten a Big Mac in nearly every state and dozens of stadiums.
Gorske was also featured in the documentary "Super Size Me" and says nearly every where he goes people call him the "Big Mac guy".
Tuesday, the McDonald's on South Military Avenue in Fond du Lac, Wisconsin will mark the occasion.
The restaurant plans to hand out buttons and free meal cards for several hundred guests.
Festivities will start at 3 p.m.
Gorske says he plans to continue with his Big Mac diet following his accomplishment.
