Bison-ten Yell Day – September 2, 2024

Bison-Ten Yell Day on September 2 is a wacky holiday that celebrates a number of things; the 200th birthday of an imaginary figure, the person who invented verbal signaling to yell at soldiers during war, the secret signals between football players, and the fact that if you say “Bison-Ten Yell” repeatedly, it sounds like ‘bicentennial.’

History of Bison-ten Yell Day

We’ve come across many crazy holidays, but Bison-Ten Yell Day takes top honors. The holiday has several strange reasons for its celebration. The phrase “Bison-Ten Yell” sounds similar to ‘bicentennial.’ The word bicentennial itself means the 200th anniversary. The reason behind the holiday can likely be attributed to someone who was born in 1813. But there is a catch; this ‘person’ apparently celebrates his 200th birthday every year. So, our imaginary figure is like the character Peter Pan, but with the same age being celebrated every year.

We’d provide the history of the day, except that this holiday is simply a goofball day, having no real purpose other than to serve as a pun. But the day does have some merit, as it honors the person who created war signals. Soldiers had to memorize the meanings behind verbal signaling or symbols. Does this sound familiar? N.F.L. players do the same.

The origins of the day are unknown, but we will continue digging to find the secret behind “Bison-Ten Yell.” Our theory is that since war signals originally invented were ten, the “Ten-Yell” likely refers to this. Now, if only we could factor the bison in somehow. Perhaps the creator of the holiday was large and formidable.
