A Smile (pass it on)

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 passed it on to him

I thought about that smile, then I realized it's 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
