If you caught the two seasons of Ricky Gervais' brilliant but hard-to-watch "The Office" (not the American remake) and the "Office" special, you might have had quite enough of David Brent. But not so fast. Gervais' Brent has been reprised on YouTube, as a training video Gervais did for Microsoft three years ago has been leaked to online video sites. Gervais is upset about the leak and Microsoft is investigating, Silicon.com reports.

Gervais is worried the leak will make fans think he was disingenuous about retiring Brent ("integrity" in Brent-speak) but will not be seeking damages from Microsoft. "Unfortunately these things happen but it's Microsoft's responsibility to let us know how it got out," a Gervais spokeswoman said. On the video, Brent advises employees with good ideas to keep them to himself:

I don't think Gates made his billions by putting his hand up in the early days and saying, "Duh, boss, I got a great idea. I'd like to see every home and office with a computer one day." "Oh, great, thanks, Gates. Ka-ching. Now get back to work, you little nerd." So keep your ideas to yourself and make em work for you. Maybe set up a rival company.
