Recently I was on a JetBlue flight to Long Beach.  A few minutes into the flight, the stewardess came around selling blankets.  Hmmm, I thought, "It's kinda chilly.  I'd like a blanket."  Then I found out that it was not just any blanket - it was an Arm & Hammer blanket.  It struck me as odd.  Why would I want a blanket from Arm & Hammer?  Is it sprinkled with baking soda?  And if so, what's the purpose of that?....
