Corrected entry: When the Oracle is talking to Neo at some point we see a piece of cigarette ash land on her lip. We neither see her lick her lips, brush it away with her hand or see it fall from her mouth and in the next close up of her face it is gone.

Correction: After we see the ash on her lip she takes another drag, the shot chages to Neo, then back to the Oracle taking the cigarette out of her mouth and exhaling the smoke. It would take less than a second for her to lick her lip. Also by her putting the cigarette back in her mouth, the cig. could have easily wiped off the ash.
