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 and 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!
