(_"Smiling Is Infectious"_)

 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
