In Monk's Café, George tells Jerry about his lack of confidence in bed with his new girlfriend Karen, and entertains the possibility that she is faking her orgasms. Elaine mentions that she faked all her orgasms while she and Jerry were dating. Jerry is flabbergasted at this revelation. Kramer takes a bite out of a bad peach, which he tries to return to the store where he bought it. This leads to him being banned from the store after he insults the owner, Joe. Meanwhile, Jerry begs Elaine to give him another shot at giving her an orgasm, which she rebuffs in the belief that sex will ruin their friendship. This causes Jerry to become bitter and resentful toward Elaine. George becomes so obsessed with his performance in bed with Karen that he experiences what seems to be erectile dysfunction. Kramer asks Jerry to buy fruit in his place at Joe’s store. Jerry is banned when Joe realizes he is shopping for Kramer. George winds up buying fruit for both Kramer and Jerry. George tastes one of Kramer’s mangoes, which causes an erotic transformation, prompting him to race to Karen's apartment. Though he impresses her with his sexual performance, Karen throws George out of her apartment when he ridicules her vocalizations during orgasm and she feels insulted after George incorrectly assumed she was faking. Elaine agrees to have sex with Jerry after concluding they have to do it to save the friendship saying "I will give you half an hour". However, Jerry again fails to give her an orgasm, and blames George. Elaine then asks: "Y'know, I'm a little hungry. You wouldn't happen to have any of that mango left?" Jerry then realizes his solution.
