Disney Announces 2012-2013 TV Lineup With Tron, Other Geeky Goodness | GeekDad | Wired.com: Another new show, which I’ve seen a short preview of and which looks like a lot of fun, is called Gravity Falls. It’s a quirky series about twins Dipper (a boy) and Mabel (a girl, as you’d guess) who are shipped off by their parents “to spend the summer with their Great Uncle Stan in the very strange town of Gravity Falls, Oregon.” The town includes the world’s most bizarre museum, within the tourist trap known as The Mystery Shack, which Stan runs. The show will star Jason Ritter as Dipper and the very funny Kristen Schaal as Mabel, and will premiere on the Disney Channel in June.
