Tom Hanks -- Standing By Conan O'Brien

Tom Hanks wants everyone to know he and Conan O'Brien go together like peas and carrots -- by posting a cryptic message on his Twitter account about his upcoming appearance on "The Tonight Show."

Hanks Twittered, "Flag on me with CoCo tonight! Going on Friday's Big Show. What WILL happen? Tune in. Hanx."

The buzz is that Friday will be Conan's last show. There are rumblings that Will Ferrell is expected to show up as well.

And that's all he has to say about that.
