"Look at the wise king, Lord Solomon; / I think he had more than one wife" (p. 293, line 35) -- Seriously questions the ideal of chastity.
"Just then the Pardoner started up" (p. 299, 163) -- The Pardoner ironically thanks the Wife of Bath for her sermon against marriage. (She hasn't made a sermon against marriage, but in the last part of the previous section she proclaimed that "I'll have a husband -- I won't make it difficult -- / who shall be both my debtor and my slave, / and have his trouble / in the flesh while I'm his wife." (p. 299, 154-158))
"Now Sirs, I'll go on with my tale -- / As ever I hope to drink wine or ale, / I'll tell the truth; of those husbands that I had, / three of them were good and two were bad. (p. 301, lines 193-196) -- Using her experience with her three "good [, old and rich] as the source of her examples, the Wife of Bath gives lessons on how a wife can gain dominance in a marriage.
"Now I will speak of my fourth husband" (p. 315, line 452). -- How she got back at him for him playing around with other women.
"Now I will tell of my fifth husband: / God never let is soul go down to hell! / And yet he was the most brutal to me" (p.317, line 503) -- Her fifth (named Jankin) was a clerk of Oxford, who boarded in the house of Alison (like in "The Miller's Tale"). -- She tells how she wooed him, how he married her then tried to control her with tales of bad wives, and how she evetually got mastery over him.
About how because he was "cool in his love" (p. 319, 514) to her, she loved her fifth husband the most.
About how she gossiped about him with her girlfriends and "often made his face red and hot" (p. 319, line 540).
About how she went walking with her future husband, Jankin, and her girlfriend, when her (fourth) husband as "at London" (p. 319, p. 550).
About how she made Jankin "believe he had enchanted me" (p. 321, line 575).
About her strong sexual attraction to Jankin, even when she's following her fourth husband's body at his funeral. "it seemed to me he had a pair / of legs and feet so neat and handsome" (p. 323, lines 597-598)
When he was 20 & she 40, she married Jankin, and gave him title to her lands and property, but "repented this sorely" (p. 325, line 632) because he begins to read to her out of a book about bad wives.
After many times forecasting that she will tell the story, she finally tells the story of the battle between herself and Jankin, begun when she "plucked three leaves / out of his book" (p. 333, lines 790-791).
"The Friar laughed when he had heard all this: / 'Now dame,' said he, 'as I may have joy or bliss' / this is a long preamble to a tale" (p. 335, lines 829-831) -- The Friar interrupts the Wife of Bath's verbal ramble. [She doesn't actually stop talking. After the Friar interrupts, she tells her tale.]
