By now it's common news that Karan Johar appears as himself for a cameo in Sujoy Ghosh's next 'Home Delivery'. In the movie, Vivek Oberoi is a script writer who wants to show his next script to Karan Johar.

But this is not the first time that Karan Johar is appearing in a movie. Exactly a decade back, he had appeared as a bespectacled young man with a weight that was on the heavier side. He was SRK's closest buddy who had his cap being dispatched from his head every now and then by the prankish Khan.

Still guessing? Well, the movie was none other than the longest running movie of all times - 'Dilwale Dulhaniya Le Jaayenge'. From a prank victim to playing a boss. Quite a long and fruitful journey indeed!
