Check out this picture of Amitabh Bachchan proudly giving the bird to everybody (I couldn't locate the online version of the image where the entire Bachchan clan is indulging in unintentional rudeness). Somebody in the polling booth is having a good laugh about the whole thing.
Props to Priya Dutt for realizing the stupidity of holding up a finger (middle or otherwise) and showing her whole hand instead.
