Upon seeing the bison become the United States' new national mammal, I, a millennial college student, became both angered AND offended. The reason for this was because I believed in my heart of hearts that our official national mammal should be the one and only Guy Fieri. 
It's plain to see that Guy Fieri should be our national mammal; He is the embodiment of America, from his flaming blonde tips to his beautifully crafted goatee. Not only does he have the spiciest tips around, but in his small hometown in North Carolina, Flavor Town, he has a collection of classic American cars. His collection includes a 1971 Chevrolet Chevelle, a 1968 Pontiac Firebird, a 1976 Jeep CJ-5, a 1996 Chevrolet Impala SS, and a 1967 Chevrolet C10 pickup. 
Now, my dear friends, the last reason that I believe the majestic Fieri should be our national mammal is because, sadly, there is only one left. Serious conservation efforts need to be put into effect to keep the very last Guy Feiri safe from harm and fed the red meat and cheese his species needs to survive. 
Thank you so much for your time and consideration in reading this, and thank you in advance for joining in our noble effort.
