A very handy tip I got via email from Microsoft.
On a blank line in a Microsoft Office Word document, type =rand followed by (PC,SC)—where PC stands for paragraph count and SC stands for sentence count—and then press ENTER. For example, =rand(2,3) will create two paragraphs of three sentences each.
Word inserts some random text based on your specification. You can use this new text for testing form controls such as text boxes or paragraph alignments.
