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 I realized its worth. 

A single smile just like mine, 
could travel 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!
