During a field trip organized by Mr. Hayden (Mike O'Gorman), the school's good-guy history teacher, Gamby (Danny McBride, who also directed this episode) looks for opportunities to impress the fetching Amanda (Georgia King) in a new episode called, understandably enough, "The Field Trip." Walton Goggins and Kimberly Hebert-Gregory also star.

The "Tricky Triangle" of Pocono Raceway is the scene today as Sprint Cup drivers gear up for the Pennsylvania 400. With its low banking and turns modeled after ones at three different tracks, this 2.5-mile tri-oval drives more like a road course than an oval, thus resulting in slower speeds. Denny Hamlin, Kurt Busch and Jimmie Johnson have each won here multiple times. Matt Kenseth is the race's defending champion.

IndyCar hits the road -- as in road course -- at the Sports Car Course for today's Honda Indy 200 at Mid-Ohio. The 13-turn, 2.258-mile layout offers drivers a little bit of everything -- elevation changes, a narrow racing ribbon and a variety of corners. Scott Dixon, with five Mid-Ohio victories, runs well here, and he'll be in a field including Helio Castroneves, James Hinchcliffe, Will Power, Ryan Hunter-Reay and defending race champ Graham Rahal.
