What is David Duchovny, aka Hank Moody from the Showtime series "Californication," thinking in this photo? What is he looking at? Why is Peter Gallagher clutching a Gore Vidal book? We snagged this special behind-the-scenes photo from the "Californication" season three set, and we're asking you to fill in the blanks.

The "Californication" Caption Contest (can you say that three times fast?) is running from now until Tuesday the 20th. We'll be accepting your submissions of funny captions for the above photo -- but only via Twitter, to accounts @SHO_liz and @Asylumdotcom. Make sure you are following both of us, and send us an @reply with a funny caption. Three lucky winners will receive Asylum T-shirts and "Californication: Season One" on DVD.

Official rules are available here, and more fine print and information are available below.

Open to legal residents of the 50 United States, and the District of Columbia who are 17 and older. No limit to number of entries. Three winners will be selected by Showtime and Editors based on funniest captions. Prizes: Californication DVD ARV: $40.00 & Asylum T-Shirt - $20.00.
