Canadian teenagers get ready for prom just like American teenagers; they plan for months, get dressed up in gowns and suits, and take photos with their friends before dancing the night away. But Canadian teens differed from Americans in one big way on Friday when Prime Minister Justin Trudeau stopped to crash a preprom photo right by Vancouver’s Stanley Park Seawall.

While taking a jog through the park, the sporty prime minister ran right through the group of teens, making for a truly unforgettable photo, CBC News reports. Trudeau’s official photographer, Adam Scotti, captured the photobomb and posted it to Twitter with the caption, “Prom season in #Vancouver.”

“We were just taking photos and hanging around talking, and then Trudeau, he just comes running,” one of the students, Constantine Maragos, told CBC News. “At first, we were like, ‘Why is the prime minister of Canada running the seawall?’ And then we started yelling for Trudeau to get in the photo.” The high school students were “stoked,” says Maragos, when Trudeau decided to take them up on their offer. In an Instagram post, Scotti called it “a memorable moment for all.”

To be clear, this wouldn’t be Trudeau’s first attempt at making photobomb magic. Just last summer, he appeared to be lurking—topless, no less—behind a bride walking down the aisle. That’s what I call a steamy beach wedding.
