World Rat Day

Nobody should ever forget Ewe on Ohio Sheep Day (July 14). No mata mata how hard they may try on World Turtle Day (May 23). If you've never heard of Dragon Appreciation Day, International Cephalopod Awareness Day, or Yell "Fudge!" at the Cobras in North America Day, it's not because they don't exist, it's simply that they needed someone to spread the word. Luckily, the fantastically zany poems of J. Patrick Lewis and Anna Raff's equally hilarious illustrations have memorialized these holidays forever. So get out your calendars -- from Happy Mew Year for Cats Day to Chocolate-Covered Anything Day, World Rat Day (April 4) calls for a year-round celebration.
