memory cells?

You see every drink of liquor you take kills a thousand brain cells. Now that doesn't much matter because we got billions more. And first the sadness cells die so you smile real big. And then the quiet cells go so you just say everything real loud for no reason at all. That'ok, that's ok because the stupid cells go next, so everything you say is real smart. And finally, come the memory cells. These are tough sons of bitches to kill.
