Michael Kimsal points out a small utility to create information he found himself needing over and over - information that looks like, but is not, personal details.

I put together a small utility to generate random user data several months back. I realized yesterday that I hadn't released the source code - I thought I had. This generates plausible names, addresses, phone numbers and social security numbers. The phone number area codes don't generally match up with the address, but the addresses are accurate in that the city/state/zip all match. The addresses are currently US-based only. The code will also generate SQL statements for you to insert directly in to your database if selected.

You can download the PHP code for yourself or just use his copy to generate some sample information when you need it.
