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 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!
