Humor Is About to Become Funny
The word "humor" comes from the Latin word meaning "bodily fluids." Medical theory of the 1500s teaches that one's basic personality is determined by a balance of internal fluids called humors and a severe imbalance causes disease. When one says, "He is in bad humor," it means he is not feeling well. On stage, standard (humorous) characters are recognized by the audience. In the modern day, these standard characters are: the hovering mother, the air-headed friend, the vain beauty queen or king who struggles to turn away from the mirror. They are usually played for laughs so when the new comedy "Every Man in His Humour" becomes popular, the term "humor" becomes associated with comedy.    
How Pieces of Eight became the Dollar *
Spain begins minting the peso de a ocho or pieces-of-eight. It has the virtue of being divisible into 8 royals or reales (ray-ALL-ehz). The wide coin is meant to be the equivalent of the German "thaler" (rhymes with dollar) which is a reference to the Bohemian valley where a major silver mine exists. Thus "thaler" means "from the valley" in Bohemia. The Spanish dollar will become the standard coin of the New World and will remain legal tender in the United States until 1857. 
Japan Invades Korea, Round 2
Here we go again. Japan has shaved down its ambitions. It will attack only Korea and leave all of China until later. 200 ships sail for Korea and land along the southern coast. As it turns out, the Koreans are well equipped and extremely well motivated all by themselves. Apparently the 1st invasion was the tip-off. Exactly what happens next is difficult to credit. Either Japan is beaten senseless and barely makes it home alive, or Japan manages to conduct an orderly retreat with most of its forces intact. Bottom line is... Korea 2. Japan: 0. Have a nice day.

- "Humorous", Words from History (PDF), Books on Words, Houghton Mifflin. “Naturally, it was tempting to present a play in which an individual had some stock characteristic--he was always bragging or always in a fury or always falling in love. [...] In 1598, Ben Jonson wrote a play in which every character was like this and called it Every Man in His Humour. Because humors were invariably played for laughs -- and got them -- humorous became synonymous with 'funny,' and so it is still.”
