A bit of fun for Dave :)

dave.rb

Ruby = 'Ruby'

class Kitson
  def initialize(name)
    puts "There is a new Kitson named #{name.capitalize}."
  end

  def is_enjoying?(something)
    ret = (something == 'Ruby')
    print "He "
    if ret
      print "definitely enjoys"
    else
      print "doesn't enjoy"
    end
    puts " #{something}."
  end
end

Kitson.new(:dave).is_enjoying?(Ruby)

print 'Press <enter> to close...'
gets

This is really just for a laugh, to make the Kitson.new... line actually do something. Not the best example of programming otherwise, except to illustrate that you can get away with pretty much anything in Ruby :)
