Smiling is infectious; you can catch it like the flu
When someone smiled at me today, I started smiling too
I passed around a corner and someone saw my grin
When he smiled I realised Iʼd passed it on to him
I though about that smile then realised itʼs worth
A single smile, just like mine could travel round the earth
So when you feel a smile begin donʼt leave it undetected
Letʼs start an epidemic quick and get the world infected!
