TWELVE OTHER SILLY FACTS

1. "Stewardesses" and "reverberated" are the two longest words (12 letters each) that can be typed using only the left hand. The longest word that can be typed using only the right hand is lollipop. Skepticisms is the longest word that alternates hands.

2. A duck's quack doesn't echo, and no one knows why.

3. In the 1940s, the FCC assigned television's Channel 1 to mobile services (two-way radios in taxicabs, for instance) but didn't re-number the other channel assignments. That's why your TV set has channels 2 and up, but no channel 1.

4. The San Francisco Cable cars are the only mobile National Monuments.

5. The "save" icon on Microsoft Word shows a floppy disk with the shutter on backwards.

6. Emus and kangaroos cannot walk backwards, and are on the Australian coat of arms for that reason.

7. In every episode of Seinfeld there is a Superman somewhere.

8. Murphy's Oil Soap is the chemical most commonly used to clean elephants.

9. The United States has never lost a war in which mules were used.

10. All porcupines float in water.

11. The reason firehouses have circular stairways is a carryover from the days when fire engines were pulled by horses. The horses were stabled on the ground floor, and figured out how to walk up straight staircases.

12. Non-dairy creamer is flammable.
