There once was a man named Gus
Whose dream was to drive a bus
He contacted the MTA
Filled out all the forms ok
Gus felt there was nothing more to discuss
The email said 'Gus, wanna join us as a bus driver?
You need to provide a sample of your saliva
Our hiring policy is strict
Won't hire a drug addict
The top priority is safety, keeping our passengers alive, uh'
