On Friday, Donald Trump accidentally tagged CFL player RJ Harris in a Tweet — and Harris's reaction was pure genius.

According to the Washington Post, the Ottawa Redblacks wide receiver was watching an episode of "Peaky Blinders" in bed when his phone began to blow up with notifications.

Harris quickly realized that President Trump had mistakenly tagged him in a Tweet instead of RJ Harris — a morning show host on WHP in Harrisburg, Pa.

“You go around Pennsylvania and you see Trump signs everywhere. The Donald Trump situation is bigger than the Reagan Revolution. Donald Trump has inspired us.” @RjHarris15 WHP580

So what did Harris do?

He capitalized on the situation in a big way.

Anticipating the media frenzy, Harris immediately took to Twitter to promote his upcoming football camp — a genius move that got the post hundreds of likes and re-tweets.

Aye, he tagged the wrong Rj Harris y’all. But while I got all y’all attention.. don’t forget... REGISTRATION IS LIVE! pic.twitter.com/5mfj5HTE4j

And that wasn't all; following the mix-up, the WHP radio host — dubbed "the other RJ" by Harris — reached out to the football player and offered to promote his camp on air.

Naturally, Harris agreed.

The duo teamed up to chat about the camp this morning.

My pleasure, you are a top-quality person. Looking forward to meeting you at your camp. Thank you for helping kids! You are welcome to come on air anytime!

But it wasn't just the other RJ Harris that found the mix-up humorous; Canadians everywhere have been poking fun at the American president's mistake.

This Ottawa football fan couldn't resist making a Star Wars joke.

While this Toronto lawyer seized the opportunity to throw a little shade at Donald Trump.

Hey Donald, you tagged RJ Harris who plays for the Ottawa Redblacks of the Canadian Football League. Ottawa is where Justin Trudeau lives. Justin Trudeau is the Canadian PM that Melania is in love with, as I’m sure you already know. https://t.co/g4yaLm3mSt

Trump has yet to comment on the now infamous RJ Harris mix-up.
