A Smile is infectious,
You catch it like the flu.
Someone smiled at me today,
And I started smiling too.
I passed round the corner,
And someone saw me grin.
When he smiled i realised
I'd passed it on to him.
I thought about that smile,
and realized what it's worth.
A simple 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
