Just ask Melanie

Melanie:
"Take your thumb off the cup. You okay?"Louis:
"Yeah, just getting old. Seems I can't smoke or laugh now without coughing."Melanie:
"Oh, well coughing's good, it opens up the capillaries,
you know when you cough you're pulling air, or in this case...smoke, into parts of the lungs that don't
normally get used, and so, coughing's good, it gets you higher..."Ordell:
"...and you definately know a lot about that. Goddamn girl, you gettin high already? It's just two o'clock."Melanie:
"It's that late?"Ordell:
"You know you smoke too much of that shit, that shit's gonna rob you of your ambition..."Melanie:
"Not if your ambition's to get high and watch TV."
