i know what the ad is about sonu anounces the winner of the contest and the winner is rahul then he wants to sing a song but can't sing then sonu gives him the honiest thingi.
i've seen the add on aaj tak.it like this Sonu:and the winner of the contest is Rahul vaidya (rahul becomes happy n when he tries 2 say somethin gale mein khich khich) rahul says: phir khanee padegi kharash ki goli Sonu says:"yehi hota hai aam kharash ki goliyo se aur kadvi bhi hoti hai" Sonu says:yellow dabur honitus
Then both sing the songdabur honitus khich khich kharash chalti bani
