test data

I seem to like having more realistic test data, to that end I have collected a large number of first names and last names over the last few years. Now I'd kinda like to collect business names. I've been searching around and cannot find anything.

I was wondering if anyone had any business names, or a place where I might download a bunch. I'm not interested in addresses or phone numbers or anything other than its name.

In return I'd be happy to share my firstname/lastname list.

OR -- anybody know where I could download a phone book?

OR -- anybody know of a big database with lots of rows?

(I played with the us census tiger data... but its to geographic points, not fun to play with)
(And not wikipedia, its mostly just text, and not fun to play with)

Thanks,
