Canadian actor and comedian Mike Myres made it back to the Studio 8H stage on Saturday night after 10 years away for a surprise appearance on Saturday Night Live and showcased his impersonation of tech billionaire Elon Musk.

But it was the moment before the credits rolled that had many people talking: Myers was spotted wearing a black T-shirt that read “Canada is not for sale,” with a Canadian flag in the middle, beside host Shane Gills and musical guest Tate McRae .

This comes after U.S. President Donal Trump‘s recent comments about making Canada the United States’ “51st state.”

After opening his vest to show off the message on his T-shirt, Myers mouthed to the camera, “Elbows up,” which is a phrase often used in hockey, meaning to protect yourself or fight back.
