Jimmy Kimmel might want to get a second wristwatch before next week, rather than try to keep changing to adapt to his current time zone. Kimmel has signed on to sub for vacationing Regis Philbin on "Live with Regis and Kelly," which shoots in NYC, but still do his own LA-based daily show. That means he will take two coast-to-coast flights every 24 hours. Kimmel plans to try to sleep on the redeye heading east after wrapping up his show in LA and to prep for his show while flying westward. That is, if he doesn’t fall asleep and tumble from his stool while co-hosting with Kelly Ripa.
