Slowly Making Sense Out of Super Mario Brothers 2

Word up, players and haters alike. I've spoken with Sam and Steve and we decided it was high time for everyone to get their Blam! on. So I've decided to post the only way I know how: a White Russian in one hand and an airsoft pistol in the other. 16 in the clip and one in the hole, bros. This naturally leads to two questions you don't want answered: HTF am I typing and about WTF will I be typing? The answer to both is science.
We all know that Super Mario Bros. 2 is a little off. It was Shigeru Miyamoto's drug baby. In Japan, though, when you get all coked up and father a bastard child, you don't kill it or give it away like we do here. No sir. They sell the hell out of it. I'm not saying that the game is terrible or anything, just that it was born a little underweight and will have a tendency to engage in self-destructive behavior.
Peach: Mario! You said you weren't gonna do any more of those door potions!
Mario: Trick, shut yo mouth before you get a turnip upside your head.
At any rate, this game did introduce to the sexiest video game vixen ever- Birdo. At least, I think Birdo's a chick. It has a bow and launches eggs at you. Sounds like every skirt I've ever known. This ambiguity just goes to highlight what and how much we don't know about Mario-2-Land. I've decided to shoulder the burden of taking the first step to understanding this narcotics-induced nightmare world: finding the mass of one of Birdo's eggs. Of course to do this, certain assumption must be made, and I'll explain each one as I make it. Should you disagree with any of these assumptions, dear reader, you can kiss my glorious Shy Guy.
The first step, as I saw it, was to establish a length scale. Mario Andretti was the only Italian Mario whose height I could find. Andretti stands a respectable 1.7 meters, but the Mario in question is super, meaning more than your standard Mario. After averaging 1.7 m with Yao Ming's 2.3 m, I came up with 2 m. Yao's gotta be the upper limit. After all, you don't want Super Mario sidelined by leg/foot problems. Mario can jog at approximately 1.33 Marios/second (2.66 m/s) while Birdo's egg (after launch) travels at 2.66 Marios/second (5.33 m/s). If the egg strikes Mario, it sends him recoiling with a speed of 2/3 of a Mario/second (1.33 m/s). If we assume the collision is perfectly inelastic... I mean why wouldn't we? The thing disappears when it hits the dude, the only logical explanation is that it lodges itself into Mario's stomach and is digested once he lands. At any rate, perfectly inelastic. So now we just need Mario's mass.
I never really got into the Soprano's or the Godfather or anything really, but I did watch enough of them to realize that any Italian that doesn't get whacked is skinny, while the remainder are quite tubby. Assuming a whacked to not whacked ratio of 4:1 for your average Italian, we can immediately conclude that 4/5 of Italians will be whacked fatties. An obese person has a BMI of 30 kg/m^2, meaning Mario's mass ought to be (4/5)*(30 kg/m^2)*4 m^2 or 96 kg. Again, he's super so I'm gonna round up to 100 kg. Combine this with a stationary Mario facing off with Birdo and conservation of momentum, you get the mass of Birdo's egg to be 33.3 kg, or 73.5 lbs. For comparison, that's eighteen Kerri Strugs. But there you have it. Egg don't lie.
