I think that this episode is one of the best episodes of Season 5. Jerry discovers that Elaine fake orgasms when they were dating and is trying to give it another shot in order to prove that he can do so much better, Elaine does not hear this and decides to leave Jerry in desperation for doing this. George worries about if his new girlfriend is faking or not hers so he panicks and loses his touch. Kramer begins buying fruit in the supermarket, but after trying to change a bad fruit for another he gets ban and tries to get Jerry to buy his fruit, he also gets caught and both of them are ban. When George buys the fruit for them and eats a mango he discovers that he has return and goes out where his girlfriend. Elaine and Jerry decide to have a sex to save the friendship, but Elaine continues unimpressed and by the end of the episode, Jerry fails in his attempt, which really make me cry of laughter. The Mango episode is great.
