The One With Rachel's Inadvertent Kiss - S5-E17
Trivia: When viewing this episode on DVD compared to viewing it on Netflix, not only are a few shots deleted on the Netflix version, but there are also shots which had been filmed differently when Rachel returns after her first interview. On the DVD, she walks over to the table, puts her briefcase down on the chair and walks to the fridge, takes out a bottle of water...and then in a closeup Chandler asks her what happened while he's holding the newspaper. But in the Netflix version, Rachel walks over to the table, and just as she puts her briefcase down on the chair she stands behind the chair, and Chandler asks her what happened - all in the same wideshot, with the newspaper lying on the table.
Answer: The statements that she's contradicting (that it is common, it happens to every guy, and it's not a big deal), are the things that a woman commonly says to a man who is suffering from erectile difficulty, typically to assuage his bruised ego. However, most men do not believe that these statements are true, as evidenced by Chandler's outburst. He's so caught up in the proof that women are lying about it that he gives himself away.
