Have you ever heard of the capybara? It's a big furry creature that I've seen in the zoo. Looking it up on Wikipedia - where I've learned everything I know - I found out that the name "Capybara" comes from "Kapiÿva" and means "Master of the Grasses." That's an awesome name. I wish I could be the master of something. Other than JezzBall.
Anyway, by further research (like finishing the second sentence from Wikipedia), I learned that the capybara's scientific name is hydrochaeris. Hydrochaeris means "Water Hog." I bet the capybara is thinking, "Thanks, Linnaeus. I went from the Grass Master to a wet pig. Grac."
And with less research (I finally went back to sentence one) I learned that the capybara is the largest living rodent in the world. Wait a second, Wikisourceofallknowledge. You can't fool me. I guess the Wikigods have never seen the Princess Bride because we all know that the Rodents of Unusual Size are much bigger than 4.3 feet long.
Disappointed, I did a little more research, this time on my Wikiatlas, Google Maps. Seems like the Master of the Googles hasn't seen the Princess Bride either because I could not for the life of me find Guilder. And it thinks Florin is in California.
Just as I was about to lose all hope in the internet, I figured it all out. The Princess Bride takes place in the past, right? So maybe something happened to Florin and Guilder like what happened to Czechoslovakia. They had a war or changed their name or something, I don't know. Reading much further into the good old capybara article I found out that there are fossils of much bigger rodents - like possible R.O.U.S.'s size. And they lived in Uruguay. Which was then known as Florin I guess.
