def self.sentences(count, &block)
  sentences = LipsumConstants::PARAGRAPHS.join.split(/\.\s*/)
  if block_given?
    count.to_i.times do |i|
      yield sentences[i]
    end
  else
    return sentences[0, count].join(". ")
  end
end

.words(count, &block) ⇒ Object

If called without a block, returns a string of dummy text with a number of words equal to count (space-separated and without any markup). If a block is given, iteratively calls the block passing each word as argument.

Gotcha:

If a block is given, the block is iteratively called passing as arguments only words more than 3 characters long. This way, nice dummy lists and menus can be generated without having to remove very short words.
