It's time to get out your red pen and mark your calendars, because ABC has announced the finale dates of its lineup, including the season finales of Lost and Grey's Anatomy, and possibly the series finales of Scrubs and… According to Jim.

The first days to get the red ink should be May 13 and May 14--make sure you keep those days open and reserve the couch in your livingroom. Lost will end its fifth season with a two-hour finale on May 13 and Grey's Anatomy will also wrap up its fifth cycle on May 14. Both should feature some major shockers; the rumors I'm hearing about the Lost character getting killed off this season even shock me, and Grey's has to decide what to do with Izzy/Katherine.

For Scrubs fans, May 6 will be a somber trip to the television morgue. Most of the principal cast is calling this season their last (Zach Braff, Donald Faison, Judy Reyes, creator Bill Lawrence), and most believe that means the end of Scrubs. Looks like one and done on ABC for the hospital comedy.

On the other end of the spectrum, May 5 means the end of a series that I think we can all breathe a sigh of relief over. According to Jim wraps up its eighth and likely final season, but given the way this series has repeatedly cheated death, I'm waiting for the dirt to pile on the coffin until I celebrate. This show is like Jason Vorhees--you think it's dead, but it always comes back to haunt you.

Ugly Betty returns from its abrupt break on May 7, and will end its season on May 21. The Bachelorette will also kick off its latest cycle on May 18… what surprises will producers have for us this time?

Nowhere to be seen on the schedule are the final episodes of Pushing Daisies, Eli Stone, and Dirty Sexy Money, which likely means they'll pop up sometime this summer.
