» GilmoreGirls

Lorelai and Rory have ridden off into the TV sunset, but 'Gilmore Girls' creator Amy Sherman-Palladino is bringing another mother-daughter series to the tube.

Sherman-Palladino will write and produce a still-untitled HBO drama about three writer sisters (who live in the same building) and their "literary lioness" mother who pays more attention to their hapless brother.

"It's a story of love, hate, family -- and finding the perfect opening line," Sherman-Palladino says, suggesting that fans can expect more of the witty, rapid-fire dialogue that was a trademark of 'Gilmore Girls.'

Island-dwelling heroes, martini-swilling Ivy Leaguers and autobiography-penning sitcom actors ... we're talking, of course, about TV land's most beloved canine cohorts.
