"Smiling is contagious, 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 he smiled I realized, I'd passed it on to him.

I thought about that smile,

then I realized 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

With a Smile!"
