Use this for when you design something and you are showing samples to your clients. Research has shown, if you put real text into your samples, no matter what the subject, the client will end up reading portions of it and not really paying attention to the design.

This handy little tool generates as many paragraphs of "Lorem ipsum" text as you need to fill up your text spaces for samples.
