This feat couldn’t be pulled off by any other person other than Akshay Kumar. The Khiladi, who is a known prankster in Bollywood, got another name in his long list of bakras. And this time, it was Bipasha Basu’s turn. Akshay was shooting for an ad at a film studio in the suburbs when Bipasha, who was there for Rohan Sippy’s film, learned of his presence. Being a friend, she went across to meet Akki but couldn’t locate him.
Akshay, who was dressed as an old man, stood right in front of Bips but didn’t reveal his identity. This went on for a good half-anhour and it was only when Akshay saw the frustration on her face, that he revealed himself !
