What happens after Amitabh Bachchan [Images] hits a lamppost?

That will be the question running through everyone's mind when his latest Cadbury teaser advertisement unveils today.

The ad shows the Big B [Images] in the backseat of his chauffer-driven convertible humming one of his classic songs, Kabhi Kabhi mere dil mein khayal aata hai.

Impressed, the driver says "Kitna meetha gana hai sir!"

On hearing this, AB abruptly stops singing and tells the driver, "Meetha, arrey yeh kya boldiya yaar tune?

He then claims that he needs something 'meetha' and instructs the driver to stop the car. He steps out in a hurry and in his haste, fails to see a lamppost. It hits him and he gets knocked out.

The driver yells out to him, and then we hear the echo of his voice go, 'Meetha Meetha!'
