"Lethal Goofin'" is the thirty-sixth episode of the first season of Goof Troop.
The episode starts with Max and P.J. seeing Tooth picking on one of their friends. P.J. accidentally boots Tooth and knocks him out. Max praises him as a hero. Afterwards, they go to get assigned to be members of the School Safety Patrol. However, Douglas Twinkmeyer, the chief, refuses their request.
But after another bully take-down, he lets them in.
- S. Scott Bullock: Tooth, "Poindexter"
- Nancy Cartwright: Pistol
- Dana Hill: Max
- Candi Milo: Melvin, Nails
- Rob Paulsen: P.J., Douglas Twinkmeyer
- This episode's title is a spoof of the film Lethal Weapon.
- Despite "For Pete's Sake" declaring Pistol to be in kindergarten during the same school year that P.J. (and Max) is in the 6th grade, this episode has Pistol attend a preschool while Max and P.J. are students at Spoonerville Junior High School. Though it could be rationalized that Pistol might be in kindergarten during this episode, and that her class is simply held at the preschool instead of an elementary school, as kindergarten is considered a form of preschool (just the highest level of it).
- Goofy, Pete and Peg do not appear in this episode.
