Hate the fact that eight hours a day
Is wasted on chasing the dream of someone that isn't us
And we may not hate our jobs
But we hate jobs in general
That don't have to do with fighting our own causes
We the American working population
Hate the nine to five day-in day-out
But we'd rather be supporting ourselves
By being paid to perfect the pasttimes
That we have harbored based solely on the fact
That it makes us smile if it sounds DOPE...
