Here's a gambling one for all you gamblers (I've found very, very few people who knew this one before I explained it to them).

Betting on horse racing has been around a lot longer than electric tote boards. Bookmakers used to have their own section of the grandstand, where they would post the odds of each horse on a sign in grease pencil.

If a particular horse was getting a lot of action from the public, and his odds were constantly being adjusted, then they'd stop using the messy grease pencil, and post that horse's odds in chalk.

Now you know why a big favorite (in horse racing, or any other proposition) is called "the chalk".

--Reno is further west than LA.

--LA-to-Tokyo is a shorter flight (in miles) than Minneapolis-to-Tokyo...but not by much! Take The Great Circle Route. Imagine drawing a semi-circle on a world map, from Minneapolis to Tokyo. As you take off from MN, you're heading NW. As you approach Tokyo, you're heading SW. This shortcut around the curvature of the planet is not enough to make it a shorter flight than LA-to-Tokyo, but it's real close.

--New Hampshire has a whopping 13 miles of sea coast.

--President William McKinley was shot at the Worlds Fair in Buffalo. He was surrounded by doctors, but they couldn't find the second bullet (the one that entered his midsection, and damaged his stomach, pancreas, and kidney, finally coming to rest in the muscles of his back). Because they couldn't find the bullet, the President died.

A few hundreds yards away from the site of the shooting was fancy new gadget on display publicly for the first time. It was a scientific breakthrough, but nobody had thought of any practical applications yet for...the X-ray machine.

(I got that one from Paul Harvey. Now you know...the rrrrrrrest of the story.)

Everybody who's into pool knows that Willie Mosconi once ran 526 balls in a straight pool exhibition, a record that still stands, and some say will never be broken.

Here's the part you don't know: Willie's run didn't end because he missed a shot or scratched--it ended because he put down his cue stick and called it a day.

Magic bullet fired by a second gunman.

"Boustrophedon" is the name of an ancient writing system in which the first line is read left to right and the next line is read right to left and so on. The word comes from the Greek for "oxen turning" and refers to the way that an ox would be used to plow a field.
