"I hope life isn't a big joke, because I don't get it." -Jack Handey

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!
