But a visit from The Humour Foundation's clown doctors soon put a smile back on his slightly bruised dial.

Dr Doctor and Dr Fairy Floss visited Ballarat Health Services Base Hospital yesterday, leaving lots of laughter in their wake.

Also known as Leon Teague and Clare Bartholomew, the pair pulled pranks, blew bubbles and sang silly songs to cheer up paediatric unit and oncology ward patients.

When they're not performing at the Canada Fringe Festival or in "Neighbours", Dr Doctor and Dr Fairy Floss are two of 55 clown doctors making hospital visits around Australia.

For Kyle, 10, who was badly bruised and concussed after falling from the top of a flying fox, the clown doctors made him smile for the first time since Tuesday morning.

"I'm starving and they took my mind off it," he said.

Ballarat Health Services medical services executive director John Gallichio said the clown doctors were always welcomed with open arms.
