The Prime Minister got in on the April Fools' Day spirit with a lighthearted tweet aimed at former "Friends'' star and ex classmate Matthew Perry.
Justin Trudeau and the actor, who played Chandler Bing on the sitcom, both attended Rockcliffe Park Public School in Ottawa.
In an appearance on Jimmy Kimmel's late night talk show last month, Perry recounted his memory of beating Trudeau up when they were students.
On April 1, Trudeau tweeted that he wouldn't mind revisiting the brawl.
"I've been giving it some thought, and you know what, who hasn't wanted to punch Chandler? How about a rematch ↕MatthewPerry?'' he wrote.
Trudeau's principal press secretary Gerald Butts confirmed it was a joke after People Magazine appeared to take the Prime Minister's tweet seriously.
