Look at the RDoc for the Array class
use str[0] to get the first element
use str[1,-1] to get the second thru last elements, or more explicitly 
str.slice(1,-1)


You might also like to use the optional second operand to the 
String#split method

irb(main):003:0> f,r="disaster a bunch of junk. 
98rh98rh98ujvi".split(/\s+/,2)
=> ["disaster", "a bunch of junk. 98rh98rh98ujvi"]
irb(main):004:0> puts f
disaster
=> nil
irb(main):005:0> puts r
a bunch of junk. 98rh98rh98ujvi
=> nil
irb(main):006:0>
