Ha Ha.  I was interpeting the pipes as empty arguments of an empty 
block, which made no sence to me.  Logical operators didn't even occure 
to me.  Seems funny now.  Thank you John and Josh for helping me see the 
light.

The || is a Logical OR Operator that returns the first true value (in 
Ruby anything besides false and nil is true).  I ran this demonstration 
in irb:
>> true || true
=> true
>> true || false
=> true
>> false || true
=> true
>> false || false
=> false

>> 1 || 2
=> 1
>> 1 || false
=> 1
>> false || 2
=> 2
>> false || false
=> false

>> 1 || 2
=> 1
>> 1 || nil
=> 1
>> nil || 2
=> 2
>> nil || nil
=> nil

>> nil || nil || 3 || 4
=> 3
