Russell Brand is tonight's first guest on Late Night with Jimmy Fallon. That's not what got my attention. This did, though. Minutes ago, Fallon typed this into his Twitter feed: "Trying a Twitter experiment around 6:00pm eastern time. Should be fun. Check in around that time." In other words, while he is taping his show for tonight. And here is this video message from Brand yesterday about wanting more Twitter followers by tonight's taping. Ergo, there shall be two celebrities, on your television late tonight, talking Twitter and Tweeting. You have been warned. As I type this, Jimmy Fallon's Twitter had 267,862 followers, compared to 84,003 for Russell Brand's Twitter.
