Metaphors in Malcolm in the Middle

[TMC]

For example, Dewey roughly represents the "id," Malcolm the "superego," and Reese the "ego." One could make the argument that Dewey and Reese's positions are actually switched, but regardless, it fits the mold well.

There's also Hal's obsessions, which arguably or perhaps totally represents the manic obsession that suburban men develop when it comes to working on the car, being the handyman who fixes the kitchen sink, or even being the master navigator that won't ask for directions. Instead of functional, "useful" obsessions, Hal's are caricatured so he trains for the DDR-esque competition, etc. instead, but the result is the same - a lot of time wasted, a lot of frustration for the family, money spent/wasted and an eventual admission of wrong-doing.
