If the only things certain in life are death and taxes, for the last 14 years you could've included the Montreal Canadiens selling out the Bell Centre.
But not anymore.
On Monday night, as the club celebrated Tomas Plekanec's 1,000th game and launched an offensive assault on the Detroit Red Wings, it marked the first time since January 8, 2004, that not every ticket to a game was sold.
The impressive streak spanned 583 games*.
The official crowd Monday night was 20,323, 965 short of a sellout.
Habs owner and President Geoff Molson told The Athletic the dip is primarily due to a new way the club accounts for individual ticket sales.
Sell out or not, Monday was not the first time in 14 years there were empty seats at the Bell Centre. However through the many creative ways sports franchises can, those empty seats always somehow manage to end up being "paid for" by someone.
Technically speaking the streak does come with an asterisk.
Using the most literal definition of a sellout, the Habs streak ended on December 9, 2014, when the club honoured the passing of Jean Béliveau by counting his long-time seat behind the home bench as empty.
