Jeremy Rupke was watching his 4-year-old son Mason at hockey practice when a question popped into his head.

“My wife and I were at the practice and we would see him saying something to the kids and the coaches,” the 33-year-old father of two told The Washington Post on Sunday. “We always know he’s saying random, funny stuff around the house. I just got curious, ‘I wonder what he’s saying out there on the ice.’”

As it turns out, quite a lot.

On Friday, the 3-and-a-half-foot-tall (his father estimates he’s 3-feet-8 in skates) novice hockey player became the sport’s latest viral sensation after his rambling on-ice thoughts were revealed in a video shared to YouTube by Rupke, an Ontario-based hockey coach whose channel boasts more than 218,000 subscribers. The roughly six-minute-long video, titled “4 Year Old Mic’d up at Hockey,” captures Mason toddling around the ice rink, chattering incessantly to himself, teammates and coaches.

Over the course of his 50-minute practice, Mason coaches himself as he works on skating using both feet. He gets confused during drills and complains about his legs being tired. But mostly, he talks about naps and a highly anticipated post-practice trip to McDonald’s, or “Badonald’s” as he calls it. As of early Monday, the video had racked up more than 3.1 million views with many — including members of the hockey community and professional athletes — describing its contents as “so pure” and “hilarious.”
