Sample Large CSVs Freely Available on Data.gov
I always forget where to look when searching for various CSV formats to help with my scripting QA. Recently, I stumbled upon data.gov again and it's like, the best govrnment website I've ever seen.
It's not only gorgeous, but it's also easy to navigate (Just hit the Data menu item at the top and search for some data.) Searching for data on their site is similar to searching for a product on Amazon. Tres bien, data.gov web dev team!
