King of the Hill is based around Hank Hill. Hank is a salesman of "propane and propane accessories." He has an obsession with his lawn, Buck Strickland, propane and the Dallas Cowboys. Hank is uncomfortable with intimacy and sexuality but has a healthy relationship with his wife, as well as the rest of his family. Hank's trademark grunting sigh in times of discomfort and the phrase "I tell you what" are running gags on the series. In contrast with his emotional distance with the members of his family, he dotes unashamedly on his dog Ladybird. Hank is also known to be passively prejudicial in a sexist manner, disallowing his son Bobby from any untraditional and "feminine" activities. Hank is married to Peggy Hill, a substitute Spanish teacher. Peggy is also a freelance newspaper columnist, real estate agent, public notary, and Boggle champion. Peggy frequently speaks the phrases "Oh, yeah!" when she exerts effort into a task, and "Oh, Peggy!", a self-compliment after a perceived accomplishment.
