Adho paaru kaakaa!

This is a grand old technique used to con small kids and grab may be a toy or chocolate that the kid isn't interested in giving you. It's simple diversion that you cause by making the kid look away by pointing in the sky and saying "Adho paaru kaakaa" (translates as "Look! There's a crow..."). Use this diversion to con the kid of the toy or chocolate.

P.S. In case you didn't get it, the child, chocolate/toy are metaphorical!
