Now, my idea of fun and your idea of fun may vary wildly ... but this is my idea of fun: Go to freerice.com and expand your vocabulary while you help end world hunger.
You play. Someone else eats. It's all good. Bookmark the site and there's no end to how many words you can learn and rice you can earn.
Thanks to Angela Pritchett for the idea!
P.S. A "gaur" is a wild ox. I missed it. I won't miss it again.
