Contrary to the image of hospitals as sterile dens of despair, the paediatric ward at Tata Memorial Hospital in Mumbai has an air of unbridled cheer. Dr Laff-a-lot sports a red bulbuous nose, yellow wig and waistcoat dotted with smileys. His vibrant outfit stands out amidst the muted colours of the ward. The moment he entered, children broke into laughter and began clapping. “Dr Laff-a-lot is here,” together they yelled, excitedly.
