Professional world is bad for honey sweet girls like Dia Mirza. The oh-so awesome Dia was supposed to shoot a biscuit commercial along with Shah Rukh Khan without knowing what she was bargaining for.

The actress had jumped at the prospect of filming SRK without much thought what she was getting into. The storyline for the ad has Shah Rukh and Dia as lovers trying to kiss and make-up after an ugly spat.

While Shah Rukh nibbles on a biscuit, Dia tries biting the same biscuit off his mouth in an attempt to anger him further.

Apparently when it came to actual filming of the ad Dia was unable to deliver because she wasn't comfortable with the sequence, also having inhibitions about eating a SRK's saliva-soaked biscuit.

Obviously she acted professionally all through, but the fact of the matter Dia just couldn't grab the biscuit hanging from Shah Rukh's mouth extending a few hours of filming to a day-long shoot. Vishal Punjabi, the director of the commercial had to keep filming till Dia finally got the shot right.

After much hard work, Dia finally pulled it off but not before, the actors gobbling down over 27 packets of biscuits between them on that day. Shah Rukh couldn't touch his dabba as he was so full.
