Smiling is infectious,
you catch it like the flu
When someone smiled at me today,
I started smiling too
I passed around the corner and someone saw my grin
When she smiled I realised I'd passed it on to him
I thought about that smile then I realised its worth
A single smile, just like mine, could travel round the earth...
So, if you feel a smile begin, don't leave it undetected
Let's start an epidemic quick, and get the world infected!
