Orca
FYI, SIZE does matter!
Of course, other elements matter too. Shape, nipples, firmness, color.
Not to worry, I just contacted the American Institute for Breast Standardization (AIBS), and they are currently developing an equation which, based on the aforementioned variables (and others that their perverted minds may think of), will provide an objective rating for the ever-important judgment of breast quality.
When such an important and transcendental mathematical advance comes to a successful materialization, Congress will approve a proposed bill that will establish compulsory breast grading on all members of the female species at the time they reach their adulthood. Thus, even if they are not kind enough to bare their goodies on the Internet for public enjoyment–I mean analysis, we still can form an educated idea of what they look like. Of course, this will be most important when picking up a girl at a bar or selecting your other half.
To build on that idea, just imagine this scenario: you get married without having previously consummated your passion in a physical way with your partner. So you are in your honeymoon, the imposing scenario of Niagara Falls gracing the view, the feel of the gentle breeze arriving at your balcony, its softness caressing your bodies, the lingerie-clad anatomy of your loved one inching closer to you, moonlight striking gently at her face, her smile brightening the sky, a romantic chill invading your body (not to mention a huge boner).
All is set for the most romantic, passionate display of sexual fireworks in history, that is, until she decides to take off her bra and suddenly, much to your dismay, a pair of shapeless, cow-like breasts manifest right there in front of your very eyes. Almost not wanting too, you take a look at the nipple area. Oh boy, big mistake, it appears like someone spilled Colombian coffee on them, a big ugly blot residing where the most perfect form of beauty known to man should have been impressed upon.
Imagine the disillusion, the sheer frustration, the suicide-inducing paranoia. Oh man, that would really suck, I mean it would really suck to suck on those hooters. So what is there for a man to do: Divorce? Infidelity?
Both scenarios are quite plausible, thereby providing substantive backing for the AIBS initiative. It is clear that knowing in advance such important information (and of course breast quality certainly should be considered as vital information) will lead to less failed marriages, since now one would now what to expect before making a commitment.
Hope they work out that equation soon. Forget about the cosmological constant, the unification of quantum mechanics with general relativity, and such absurd pursuits; breast-concerning studies are the real issues that scientists should be devoting their energies to. 
I just realized that I might have drifted off subject just a tiny bit
So, to get this discussion back on tracks, here are a few more proposals:
Tiffani Amber Thiessen: sure, they are silicon-stuffed but can you honestly tell me you have never fantasized about them?
Jenny McCarthy: she surely is very well equipped in that area. Make that, she is well equipped in all areas.
Carmen Electra: I could drawn in the juiciness of those floaters anytime.
Oh, almost forgot Orca are we talking about the same Anna Nicole Smith?
