Lethal Weapons (3x7)
: 22, 2001
Lois joins Bonnie's martial arts class for fun, and soon becomes the course's star pupil. When Quahog gets overrun with leaf-watchers from New York, Peter decides to use his wife's new fighting skills to try and run them out of town. The plan succeeds, but the violent tendencies he awakens in Lois may not be so easy to bring back under control again.
