A 56-year-old man in eastern Ontario is wanted by police on a mischief charge, after he allegedly threw a propane tank into a fire during an argument with his son’s girlfriend over whether the Earth is flat or round.

Police say the argument broke out among three family members who were sitting around a campfire at St. Lawrence Park, in Brockville, Ont., on Monday. A woman refused to back down from her assertion that the Earth is flat, and her attitude ultimately pushed her boyfriend’s father over the edge.

After attempting to drop several truth bombs about the shape of the planet, the 56-year-old man started throwing items into the fire, including a propane tank.

Police and firefighters were called to the scene of the argument to extinguish the flames.

Dude is my hero.
