Betty, as usual, is not invited.

The Adrienne Shelly Foundation, a nonprofit organization benefiting female filmmakers, has wrangled a host of celebrities into offering up a lunch date for auction on Ebay. Bidding starts at $500.

Notables include Mad Men star Jon Hamm (lunch for two with Don Draper currently runs $660), Paul Rudd (current bid: $985), and David Schwimmer (will eat with you for $520).

It’s great that all these top male actors are volunteering their chowing services to a foundation that benefits women in Hollywood—-though roping in Hamm and Rudd will, let’s face it, bring in mostly female dollars (the Schwimmer thing I can’t explain). Also volunteering their lunch hour to the foundation are a few females, including Felicity undergrad-turned-Bond girl Keri Russell (current bid: $560) and ER alum Julianna Margulies (currently unbidden at $500).

Don’t worry, Julianna: Nobody wants to eat lunch with Patrick Duffy, either.
