Take part in the Odd Socks for Animals campaign by wearing mismatched
socks. When you wear odd socks, people are bound to comment -- which gives
you an excellent chance to talk about the campaign your odd socks represent.
(Kind of like a ribbon campaign, but much more visible!) It's cheap, it's
easy, and it even promotes recycling -- at last there's something you can
do with all those unmatched socks your dryer keeps spitting out. So get out
that bag of mismatched socks you've been saving "in case the other one turns
up" and make a statement against cruelty!
