I get similar calls from folk at work wishing to 'speak to the business owner' in order to save me some money on my phone plan.
To which I reply 'OH MY GOD...are you the guy form that Slumdog millionare movie?? Man.... I love that movie!! - hello..hello..
...beep...beep...beep..
works every time..
Indian call center chick called me once:
