Diesel has launched in India, and for their launch-party they invited celebs with a little bottle of crocodile tears.

"Inspired from the dubious factoid that India has the largest number of Diesel fakes in the world, Diesel’s launch party in India was called the "Fake Party". Celebrities including movie stars, fashionistas, and other A-listers had to be invited to this party.
To invite the celebrities to this party we sent them "Tears of Joy" - 100% Natural Crocodile Tears that was actually a bottle of glycerine. This unpretentious dig on the ever-socialising celebrity lifestyle established an instant connection with the celebrities. Some of them blogged about it, few asked for an extra piece to play a prank on their friends, and almost all of them (438 out of 500 invited) turned up at the party to revel in its mad fun - this time, for real."
