兩個瓢 Two Gourds At One Slice
大聖笑道：「這妖精沒眼色，把老孫認做個瓢頭哩。大圣笑道：「这妖精没眼色，把老孙认做个瓢头哩。
逐句解 Line by line
Kept in a deep-mountain ancient cave, and in the field it has earned its merits.
The line before the punchline, and it is deliberately flat: where the thing is stored and what it has achieved. Every recital in this chapter slows down before its last line.
"Catch it under this monk's crown of yours, and one pare of it makes two gourd-dippers."
攙著 takes the light zhe. 天靈蓋 is the crown of the skull, the fontanelle plate — a real anatomical term. And 瓢 is a dipper made by halving a gourd and scooping it out, which is exactly what a skull cut in two looks like. It is the only line of the poem with a person in it.
The Great Sage laughed: "This demon has no eye for things at all, taking old Sun for a gourd-head."
沒眼色 — no eye for the colour of things — is the same insult Bajie threw at Wukong a few passages back. And 瓢頭, gourd-head, is Wukong turning the demon's own image into a name for himself.
The poem's punchline is a piece of kitchenware. A 瓢 is the commonest object in a Ming household — a halved gourd for scooping water — and the sabre's boast is that a head is one blow away from being two of them. Domestic imagery for an execution is a very old way of making violence land.
Wukong's reply refuses the frame entirely. He does not dispute the sabre; he objects to being mistaken for a gourd, which is a complaint about categories rather than about danger. The demon has made a threat and been answered with a correction.
