Quahog residents brace themselves for the annual return of the "Leafers," obnoxious tourists from New York who flood the town to view the autumn foliage. Inspired by Bonnie's (voice of Jennifer Tilly) impressive figure, Lois (voice of Alex Borstein) joins a Tae-Jitsu class taught by Jared (voice of Peter Gallagher). Lois turns out to have a great talent for fighting. Peter (voice of Seth MacFarlane), disturbed that Jet fans have taken over The Drunken Clam, tries posing as a man-eating tree to scare off the tourists. When he learns of Lois' fighting prowess, he puts up a sign on his lawn, giving folks the opportunity to "Fight the Ass-Kicking Housewife" for ten bucks. Lois, naturally, doesn't go along. Peter feels threatened by Lois' newfound sense of power, and tries to get her to quit. She goes along until Jared asks her to join his advanced class. Soon, Lois is taking on all comers. One night, she interrupts Peter's viewing of "Speed 3: Glacier of Doom" to demand sex. The next morning, a frazzled, humiliated Peter cries to Brian (MacFarlane), "Last night, Lois was the man." When Stewie (MacFarlane) attacks Peter with a baseball bat, they bring him to a therapist, who points out that the Griffins have a lot of anger in their household. They go home determined to smooth things over, but when a round of therapeutic role-playing goes awry, all hell breaks loose. This episode features the vocal talents of Michael Chiklis.
