Smiling is infectious
You catch it like the Flu
When someone smiled at me today
I started smiling too
I walked around the corner
And someone saw me grin
And when he smiled, I realised
I had passed it onto him
I thought about the smile
And I realised it's worth
A single smile like mine
Could travel round the earth
So when you feel a smile begin
Don't leave it undetected
Start an epidemic
And get the world Infected
