To celebrate the day, Trudeau rocked some super geeky Star Wars socks while meeting with Ireland's Prime Minister, Enda Kenny.
The chill AF world leader appropriately chose one R2-D2 sock and one C-3PO sock (they're a team after all) for the occasion and documented his very nerdy sartorial choices on his Instagram story.
And because Trudeau knows what the internet wants, he later posted a closeup of the socks on Twitter, and wished everyone a happy May the Fourth:
Then Twitter, as it does with all things Star Wars, went into freak out mode.
These are the socks you’re looking for. #MayTheFourthBeWithYou#GuerreDesÉtoilespic.twitter.com/AXTQkgmkYH
