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
And when he SMILED, I realized I'd passed it on to him.
I thought about that smile, and 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!
