That was a little rhyme that my English teacher used to help us remember irregular forms of adjective “best”.
In New York cops are called “New York’s Finest” and firefighters are called “New York’s Bravest”.
But let’s not forget about the lesser known adjective described services:
NYC Department of Sanitation Workers: “New York’s Strongest”
Corrections Officers : “New York’s Boldest”
TLC Enforcement Officers : “New York’s Proudest”
EMS drivers and paramedics : simply “New York’s Best”.
And they are all exactly that, and more.
