可有頭沒頭 Look Whether It Has A Head
行者道:「你看看可有頭沒頭。」八戒笑道:「原來是沒頭的,我道如何築他也不動動兒?」行者道:「師父在那裡?」八戒道:「在殿裡與王敘話哩。」行者道:「你看看可有头没头。」八戒笑道:「原来是没头的,我道如何筑他也不动动儿?」行者道:「师父在那里?」八戒道:「在殿里与王叙话哩。」
逐句解 Line by line
Pilgrim said: "Take a look and see whether it has a head or has none."
看看 doubles the verb to make the looking sound casual, which is the whole of the trap — just have a quick look. 可有頭沒頭 puts both branches of the question into five characters and leaves Bajie to discover which one is true.
Bajie laughed: "Why, it has no head at all! I did wonder why it never so much as stirred when I raked it."
原來是 marks something turning out otherwise than supposed — the same formula Wukong used of the gong on the road. 動動兒 doubles the verb and takes the suffix at ér: not a twitch out of it.
Pilgrim said: "Where is Master?"
那 is the questioning nǎ here, not the pointing nà — five times against thirty-four so far in this chapter, which is a fair measure of how much work one written character is doing. Eight characters, own he-said, own quotation closed: it stands alone.
Bajie said: "Inside the hall, talking with the king."
敘話 is to sit and talk things over at leisure — catching up, rather than conferring. The king has spent this entire scene indoors and unaware, which is where the chapter has kept him since the wine was declined.
The joke lands in two moves and Wukong makes neither of them explicitly. He asks Bajie to check for a head; Bajie checks, finds none, and immediately supplies the inference himself — that would be why it never moved. He has demolished his own case and he laughs while doing it.
What is funny is that the reasoning never falters. The nine holes were real, the corpse's stillness was real, and the connection he draws between them is correct. Only the conclusion he wanted has quietly vanished, and he does not appear to notice it going.
Then Wukong changes the subject in four characters. The argument is not won, or conceded, or mentioned again — it is simply over, because he has what he came for and Bajie was never the point of it.
