Original Blog Post
"In my favourite places, the smartest thing around is a particular kind of monkey. Vexatious at times, volant and vogie at others, a vervet gets in anywhere and delights in teasing cats and dogs alike. As the upstart monkey in this business. I can think of no better mascot. And so let’s launch our vicenary cycle, our verist varlet, the Vivid Vervet!"
