Today in clever marketing ploys: the new poster for 'The Sitter' features a working phone number that allows anyone to leave a message for Jonah Hill's titular child care professional ("professional"). Cute! Check out the full text of the message, as well as the poster, ahead.

'Sitter' fans -- an odd term since the film isn't out until December, but go with it -- are encouraged to call 917-409-7838, which houses the following message:

"Hey, you've reached Noah Griffith, I'm not home. If you're calling about a babysitting gig, please post a photo of yourself in something along the lines of a bikini or [unintelligible] lingerie on my Facebook page, which is Leave a message!

Thus far, Hill hasn't returned our call yet -- he's reportedly actually answering calls at random -- but hope springs eternal at Moviefone HQ that he will. Check out the poster below.

Directed by David Gordon Green ('Pineapple Express'), 'The Sitter' heads to theaters on Dec. 9.
