This year’s fall TV lineup couldn’t be geekier. With two new network shows breaking out the beakers and several returning shows ratcheting up the scientific tension, it seems lab coats have taken over the small screen, no doubt to the chagrin of grizzled cops, desperate housewives and testy lawyers.

In this gallery, we tell you which shows should top your TiVo queue, which ones are as fun as math camp, and which you can watch with your girlfriend. (Just kidding, we know you don’t have a girlfriend.)

It seems there's someone out there more obsessed with Knight Rider than I. His name is Juha Terho, he's Finnish, and, according to his Web site, he graduated from the University of Helsinki Law School last Friday. Congrats, Juha. Anyway, Juha has a history of obsession with KITT, the 1982 Trans Am that was the star of the classic TV show (Hassel-who?). From the tender age of seven, he dedicated his free time to drawing KITT's dashboard, a pursuit culminating in the Photoshop masterpiece that eventually made its way into the series' season-one DVD set. Check out his progression here. —Joe Brown
