- everything in "Clip Job", esp. when Harry Medfly made the constant references to television shows
- the Apocalypse Now flashback in "In the Nam of the Father" ("You have no right to judge me. You have a right to kill me, but not to judge me. No, wait. Judge me, don't kill me. Yeah, that seems better.")
- the "pretentious role-playing from a movie nobody remembers" in "Gripes of Wrath"
- the "Call the police"/"Queen of hearts" scene in "The Mallardian Candidate"
- anytime one of Duckman's alternate selves appeared in "The Once and Future Duck"
- the high school flashbacks in "From Brad to Worse"
...and many more. Lord, how I love and miss this show.
