Man Tries To Drink One Gallon Shamrock Shake


At first, the Shamrock Shake from McDonald’s sounds like a fun time. But despite what your mom told you growing up, not everything that’s green is good for you. The St. Patty’s Day concoction contains reduced fat vanilla ice cream, high fructose corn syrup, whipped cream, and a maraschino cherry.

A large 22 oz. cup contains 840 calories, 24 grams of fat, and 117 grams of sugar. This dude would attempt downing almost 6 of those in 1 sitting. We’ve seen 2 guys go head to head in a one cup chug off and 2 interns funnel 1 cup’s worth of Shamrock Shake each, but an entire gallon? Most stomachs get super angry after just 1 serving, much less 1 gallon.

So, how did he fare? Go to for the full story.
