Speaker 3: Come on, they were not that huge. 
Speaker 1: I'm tellin' you, she leaned back, I could see her brain. 
Speaker 2: How many perfectly fine women are you gonna reject over the most superficial insignificant things? 
Speaker 4: Hold it hold it. I gotta side with Chandler on this one. When I first moved to the city, I went out a couple of times with this girl, really hot, great kisser, but she had the biggest Adam's apple. It made me nuts.
