It's a truth universally acknowledged you shouldn't talk politics at the dinner table, and when it comes to the divisive dish of Hawaiian pizza, maybe politicians shouldn't talk dinner either.
Iceland's President Guðni Th. Jóhannesson recently revealed his distaste for pineapple as a pizza topping when taking questions from students at a local high school.
He told the class that if he had the power to change the law, he would ban it in the frosty North Atlantic island nation.
In a statement Mr Jóhannesson told the Canadian Broadcasting Corporation: "I like pineapples, just not on pizza. I do not have the power to make laws which forbid people to put pineapple on their pizza. I am glad that I do not hold such power. Presidents should not have unlimited power… I would not want to live in such a country. For pizzas, I recommend seafood."
Debate soon erupted on Twitter.
"Most of the world flounders with political division. Iceland's president has a 97 percent approval rating and is waging a war on Hawaiian pizza," Tom Faliszek wrote.
"Huh, I thought Iceland was supposed to be a nice place," Erik Belsaas said.
Rob Willock tweeted: "That's #Iceland off my travel bucket list after its president disses the Hawaiian, the King of #Pizza IMHO."
"Iceland's President is a wise man. Say no to Hawaiian Pizza! #BanPineapple," Daniel Eland wrote.
Despite being called Hawaiian pizza, the ham and pineapple delicacy is reportedly a Canadian invention.
