Barstool's Dave Portnoy is a number of things, but being aware of geography is not one of them. In a posting to X prior to Game 1 of the Buffalo - Boston series, the Bruins backer trolled the Sabres, asking why anthem singer Cami Clune sang both the Canadian and US anthems prior to games. 

"Buffalo's been out of the playoffs so long, they forgot what country they live in?"

The Sabres have played both anthems since their inception in 1970. Most NHL clubs perform both anthems when a Canadian club is playing a US club, but Buffalo always plays both, since a sizable chunk of their season ticket holders are Canadian and their arena is less than two miles from the Canada - US border.
