The Toronto Blue Jays' J.A. Happ has faced numerous challenges.
For one, there was the Pittsburgh Pirates' Andrew McCutchen.
Trying to get to the NBA and learn guitar also proved to be troublesome.
But above all else, there is one obstacle that growing up in what Happ called the "one-stoplight" town of Peru, Illinois, could have never prepared him for: bagged milk.
"You guys [in Canada] sell milk in bags, and I don’t really get why, or what you do then with the bags," the 33-year-old told Sportsnet's Kristina Rutherford.
Among his grievances toward the dairy's packaging were its perceived messiness, which was the result of a misunderstanding about how to properly use the bagged milk and, consequently, the inefficiency of the container.
But fortunately for all other current and future baseball transplants, Happ isn't simply confused and complaining; the left-handed pitcher has plans to help his fellow foreigners.
"We need a memo sent out to all American players on how Canada dispenses its milk," he jokingly proposed.
And if they're anything like Happ, who says he's never purchased any of the country's curiously contained milk, there's little time to waste.
Imagine how much better the Blue Jays would be with a little more calcium!
