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 he SMILED, I realized

I'd passed it on to him.

I thought about that smile,

then 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.
