11 Hank and the Great Glass Elevator

On a day-trip to Austin for Bill's 40th birthday, Hank moons the former Governor of Texas, Ann Richards (guest-starring as herself), leading Bill to take the blame and eventually enter a relationship with her. Bill's time with her leads to a fateful encounter with the last person he would ever expect to see again: his ex-wife, Lenore. Meanwhile, Peggy and Bobby try hamburgers grilled on a charcoal-powered barbecue for the first time -- and run afoul of Hank's none-too-subtle loyalties to propane when he discovers their stockpile of charcoal briquettes upon returning.
