Client Meeting (Marketing-Advertising) blunders- My all-time favourites:

“We can milk Rani Mukherjee to the fullest.”
(X convincing marketing team to use Rani Mukherjee as a brand ambassador for Y brand)

“I want to see a cock in every Indian child’s hand.”
(Brand Manager on vision of Coke. You must excuse his South Indian accent. Of course, he meant ‘coke’.)

A (at a Client meeting-mistaking B to be from the Client): Hullo. How are you? So, the sales figures doing well?
B (confused): Sir, I work in your company.
A (turns away and then looks at B again angrily): You should still know the sales figures.
