4. Shame

Fed up with his bully, Kevin, Malcolm beats him up, but it turns out that Kevin is only a 7-year-old, something Malcolm learns after he beat him up. Malcolm feels guilty and tries to clear his conscience, but ultimately fails, especially after Hal accidentally beats up Kevin's 15-year-old brother. Concurrently, Dewey is injured while climbing a tree, so Hal cuts it down, but they soon miss the tree, and so Hal plants another. Francis decides to steal the slides for the military academy's vulgar sex education slideshow, but he finds some embarrassing slides of Commandant Spangler ( Daniel Von Bargen ) in his office, which he replaces with the original slides. However, Spangler realizes this, and instead shows the cadets embarrassing slides of Francis.
