Shahrukh Khan was at his usual charming best at the music launch of his next film, RA.One. He was fielding all questions with his unmatchable wit and ensured that everyone was thoroughly entertained. When asked, which superhero does Karan Johar remind him of, he joked and said, “Superman ko apna naam Karan Johar rakhna chahiye.” (Superman should rename himself as Karan Johar). SRK said this to appreciate the fact that Karan dons so many hats and that too so efficiently. The evening of the music launch will not be easily forgotten.
