Hank and the Great Glass Elevator

The guys go to Austin for Bill's birthday.  At the hotel, they decide to have some fun by mooning people through the glass elevator, and Hank accidentally moons the former governor of Texas, Ann Richards.  Richards takes a liking to Bill, and they start dating. Bill's new relationship is threatened when his ex-wife, Lenore, shows up and seems to be interested in him again.
Meanwhile, Peggy and Bobby discover that they like charcoal-grilled burgers better than burgers cooked with propane, and they try to hide their charcoal addiction from Hank. When Hank finds a lone briquette under their stove, he demands some answers, and a choice.
