I have, at two different companies, in fact, and 1000-line chubbers at a couple of others. The 5000 line functions weren't great, but they weren't that bad because the code was pretty straightforward, doing one thing after another top to bottom. Over time they all got gradually broken down into smaller functions/methods. (Disclaimer: I was not the original author of any of these.)
