I don't understand why someone would want breast implants. Well, okay, I can understand why someone would consider it, but it astounds me that anyone ever goes through with it. Maybe that's just because I have a decent pair of my own. But fake breasts just look... weird, and especially obvious if they're out of proportion to the woman's overall weight. Looking unnatural is just... well, it's unnatural.
Besides, if your chest is too large you end up having back problems.
Oh, and as an example of sorts, see South Park. There was an episode dealing with breast implants, I think.
