the green mile is when you drive back to school after skipping class to smoke pot. the only parking spots that are left are at the end of the parking lot, so the walk back to school seems like a "mile" because its long and because of the fact your ripped out of your gord from all the bud you smoked, thus the "green". Then theres the analogy to deathrow as there are about 500 windows in the school and all that has to happen is a faculty member see you coming back from off campus high and your dead.
dude wheres brian? ah hes fucked man he got caught walking the green mile.
