We're guessing he didn't want fries with that.
According to Stonie's math, that's about 1 1/4 gallons packed with 5,740 calories and 805 grams of sugar.
During the "7 Shamrock Shake Challenge" attempt, Stonie pours the green concoctions into two jars, adding whipped cream and maraschino cherries. He then chugs away while wrestling with massive brain freeze.
Incidentally he chases the feat with a cheeseburger. What a showoff.
Stonie recently set a world record by eating 182 slices of bacon in five minutes. A week earlier, he consumed 14.5 pounds of birthday cake.
Imagine those two eating at McDonald's together, if you dare.
