The Municipal Corporation of Delhi (MCD) has come up with a unique ad campaign to raise sanitation awareness in the city. And for this, it is going to use none other than Mr Thu Thu Kumar (who spits at public places), Mr Su Su Kumar (who urinates at public places) and Mr Koodha Kumar (who throws garbage at public places). These characters will try and instill civic sense among the Delhiites through bus kiosks, hoardings, television and radio.
