how to avoid lung cancer

i finish two cigarettes on the way home. when i get in, i go straight to the bathroom and brush my teeth. i brush every crevice… my gums, my tongue, the roof of my mouth, and i get way back there – my tonsils and then into my throat and then way way down, all the way into my lungs and i brush those real good. i brush them like a chimney sweep until they’re like new.
