 The scene where Lever, Johnny (qv) demonstrates different kinds of  laughter and makes fun of Khan, Shahrukh (qv) while  Roshan, Hrithik (qv) stands next to him, smiling, is an insider  joke referring to the Coke wars the two stars had with each other.  Hrithik supported Coke, Shahrukh Pepsi. A Pepsi commercial made fun  of Hrithik, which created quite some outrage among his fans and was  widely reported in the media.
