Karan Johar thinks he should drop the alphabet 'K' after watching 'Lage Raho Munnabhai' in New York. So, is he saying he won't be superstitious any more on K? "Superstition is state of mind. With determination and sincerity, one can overcome superstitions and gain power. I want to overcome this and become more powerful. That is not to say I will drop the K from my name and become Aran!" laughs Karan.
