So there I was, watching a hockey game and, embedded in the ice, was a ribbon.

>And you thought: "Why the ribbon?"?
Well ... yes. So I grunted something and my wife said: "It's a breast cancer awareness ribbon".
So I googled for "ribbons" and saw there were a jillion of them ... so I thought I'd mention a few.
Each is in support of some cause, though (it seems) many causes use the same ribbon colour.

Here's a sample:

support the Troops	Breast Cancer	Health Issues Child Abuse Violence against Women	the Environment Missing Children Organ Donations	Charitable Causes anti-Aids Drug Abuse	signifies Mourning Literary Rights
Free Speech Anti-tobacco Bring Home the Troops	Feminism Violence against Women	anti-Racism World Harmony	anti-Political Correctness Break Chain e-Mail	pro-Life	Brain Tumour Awareness
