The Canadian PM's choice of socks has prompted Twitter banter involving Star Wars' Luke Skywalker and Star Trek's Captain Kirk.
Justin Trudeau brazenly wore socks depicting Star Wars favourite Chewbacca at a business forum in New York City, resulting in a tweet of disapproval from the Starship Enterprise's commanding officer.
Actor William Shatner, in a nod to the "rivalry" between Star Wars and Star Trek, tweeted: "@JustinTrudeau I thought we were friends. Chewbacca socks?"Hey, at least this time they match.
