Nicholas tells him, the next Monday, waters twice as great as Noah’s flood will cover the land, exterminating all life. The carpenter believes him and fears for his wife, just what Nicholas had hoped would occur. Nicholas instructs John to fasten three tubs, each loaded with provisions and an ax, to the roof of the barn.
"I had a vision from God, would you like for me to tell you about it? I have foreseen a terrible event.
On Monday night, they will sleep in the tubs, so that when the flood comes, they can release the tubs, hack through the roof, and float until the water subsides. Nicholas also warns John that it is God’s commandment that they may do nothing but pray once they are in the tubs—no one is to speak a word.
Monday night arrives, and Nicholas, John, and Alisoun ascend by ladder into the hanging tubs. As soon as the carpenter begins to snore,
Nicholas and Alisoun climb down, run back to the house, and sleep together in the carpenter’s bed. In the early dawn, Absolon passes by.
Hoping to stop in for a kiss, or perhaps more, from Alisoun, Absolon sidles up to the window and calls to her. She harshly replies that she loves another. Absolon persists, and Alisoun offers him one quick kiss in the dark. Absolon leaps forward eagerly, offering a lingering kiss. But it is not her lips he finds at the window, but her “naked ers” . She and Nicholas collapse with laughter, while Absolon blindly tries to wipe his mouth.
From all the pranks and noise coming from the house, it attracts many townspeople. The carpenter tells the story pf the predicted flood, but Nicholas and Alisoun pretend it didn't happen and he is just mad. The townspeople laugh that all have received their dues and The Miller merrily asks that God save the company.
