This was one of my favorite shows and still is…

“Chandler! Okay, let me get this straight, it’s okay for you to flirt, but not for me.”
“Oh, I’m so glad we cleared that up. Look, I’m sorry, some things are different for men and for women.”
“Go on, teach me something about men and women.”
“Okay, I’ve already tought you so much already, but whatever. See when you flirt with a guy you think, ‘I’m just flirting, no big deal.’ But the guy is thinking, ‘Finally! Somebody who wants to sleep with me’!”
