Using 'return' will break you out of a method. If you want to use it to 
break out of a loop, wrap your loop in a method. i.e.:

#!/usr/bin/ruby

@colors = %w(red blue yellow green)
def find_yellow
  @colors.each do |color|
    p color
    return color if color == 'yellow'
  end
end

puts "I found #{find_yellow}"

HTH,

Josh
