Retired prison guard Don Gorske dedicated his professional life to the penal system, but his (shockingly) still beating heart belongs to the McDonald's Big Mac. The 57-year-old Wisconsin native broke his own Guinness World Record Tuesday when he consumed his 25,000th Big Mac. Gorske, who was featured in the 2004 documentary Super Size Me, says he likes counting things, and is "probably obsessive compulsive." And the burger fanatic has no intention of stopping: "I plan on eating Big Macs until I die."
