Check out this article in Wikipedia. It's about a particular linguistic oddity....
"Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo" is a grammatically correct sentence used as an example of how homonyms and homophones can be used to create complicated constructs.
I had to keep reading and squint for a while before I got what it's saying, but yeah, it does work. That doesn't make it any less freaky, though, LOL!
I love stuff like this. :)
