Odd Facts of the Day

First, the NWS got it partially right. We had a few inches of really wet flock snow overnight. But, it warmed up to the 40s during the day so about 80% of the stuff melted, leaving wet and mud to run rampant. Now this evening, the temperatures are already in the low 20s, so I expect the morning to be an icy slipping and sliding affair. On to more interesting fodder.

Here are three trivial questions featuring the odd facts of the day. They were brought to my (rather odd) mind by the plethora of factoids presented by the announcers at tonight's New England Patriots versus Indianapolis Colts football game. Do you know the answers?

• NERF (as in Nerf Ball fame) is an acronym for what?
  

• The very first American 911 system call was made on February 16, 1968. Who made the call and who answered the call?
  

• An average person typing an average text corpus in English uses one hand more than other, which hand is used more? For extra credit, what is the percentage of characters typed by each hand? (You can assume a standard typewriter layout - no Dvorák or other special keyboard.)
  

(Answers are in the first comment so you can check yourself. But be honest and no fair Googling!{*grin*})
