It is International Day of Happiness today and these clowns are wasting no time in bringing cheer to those who need it most. Every last Saturday of the month, the volunteers visit the paediatric wards of KK Women's and Children's Hospital to sculpt balloons, perform magic tricks or just be silly, all to make the children smile. The members of the Caring Clown Unit include (from left) Shootie, Rong Er and Rojo, who are seen here comically searching for butterflies in a hospital ward - to 11-year-old Vinitha Suresh's delight. Formed in 2004, the not-for-profit group aims to make a positive difference in the lives of hospitalised patients, their families and caregivers by spreading warmth and cheer through humour. With ages ranging from 26 to 62, the 11 active members are a motley crew from various walks of life, with the motto, "I clown because I care".
