The other day I stopped at a chain coffee shop that always offers ten cents off your purchase if you correctly answer the multiple-choice trivia question they have written on a chalkboard below the coffees of the day.
The question on this particularly day was, "What metal is liquid at room temperature?"
Choice d.) was mercury, which I correctly answered. Was this fact something I had learned in school? Hell no; I was an English major. I didn't learn anything having to do with the real world since my junior year in high school or so.
I learned it from Mark Waid, Grant Morrison, and company's weekly series 52, which featured The Metal Men, whose boisterous member Mercury announced the fact that he was the only metal liquid at room temperature so often that it was basically his catchphrase, a nerdier version of "Hulk smash!" or "It's clobberin' time!"
So thanks DC! You saved me a dime! (And not for the first time!) That's like getting 1/30th off of one of your comics!
