The Joke
A father is exercising and mutters to himself that "exercise is a real pain in the ass." His young son overhears and says "What?" The father, embarrassed, quickly explains that it was "just a bad turn of phrase" and that "in the ass" is merely an intensifier that "adds emphasis to the preceding phrase." The child accepts this with a simple "Okay."
In the final panel, the child has applied this lesson. He tells his mother: "Mom, this lollipop is a real pleasure in the ass." The child has logically extended his father's explanation -- if "in the ass" adds emphasis to negative phrases, it should work for positive ones too.
The Humor
The comic exploits the gap between how adults understand idiomatic expressions and how children process language literally and logically. The father's hasty, technically accurate explanation of "in the ass" as an intensifier backfires spectacularly because the child applies the rule consistently, unaware that the phrase carries vulgar connotations regardless of context. It is a classic example of children following linguistic rules more faithfully than adults, who rely on unspoken social knowledge about which phrases are acceptable. The result -- "a real pleasure in the ass" -- is both grammatically consistent with the father's explanation and hilariously inappropriate.
