"A smile 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 realised I'd passed it on to him. I thought about that smile, then I realised 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." Spike Milligan
