There's dose and rose and lose, and goose and choose, cork and work and card and ward. A dreadful language? Man alive! I'd mastered it when I was five!
I really enjoy quirky things, and language has some great quirks. In all my travels, I strive to pick up a little of the local languages. I believe that language not only gives us a way to express thought, but to a certain extent, shapes how we think.
In fact, I have a list of neat words :)
