Two ya never lose. One of 'em requires that there be a baseball game on TV.
1. If you are in Bristol, TN, which is closer- Memphis TN, or Windsor Ontario? *
2. Get a standing bet that a batter fouls off the next 3-2 pitch. A buck for you if he fouls it off, a buck to the sucker if there is any other outcome. Sounds like easy money to the sucker, but it's corn in the crib for you. Any 3-2 pitch, the first or nth of the at-bat, batter fouls it 60+% of the time
* Windsor, by any measure, air miles or by road.
Forgot another good one: which state is easternmost in the USA, and which is westernmost? Most folks will try to guess if HI has an island west of AK, or if FL sticks out further than ME. The answer to both is Alaska. There is an aleutian island on the other side of the int'l date line, making it the farthest east, as well.
