10 pound breasts
Those... are a lot more than ten pounds.
I remember reading breast weight can very roughly be estimated at 1.6 lbs times the cup size (A=1, B=2, C=3, etc.). I am not a breast scientist, so I have no idea if that's true, but if we assume it's true, Samus looks like she's got Ds, maybe DDs. So she'd have right around seven pounds of breast.
This is much better than talking about which Metroid games are canon.
Never heard that before, but that's interesting. Is that for the two breasts combined, then? My friend's wife, who has very large boobs (understandably since she's a bit heavy,) said her's probably weigh about 5 lbs each. I couldn't even guess what cup size you would call her. F, probably.
