Which one of the two reached 100 million sold first?

the chicken

Game Boy did.

The PS1 didn't reach 100 million PRODUCED until May 18th 2004, which is after the Game Boy/Colour had stopped being shipped.

You know it's the egg you Sonic hater f00'!

you can't have a chicken egg without a chicken. Also, I don't hate sonic, just his newer games. I loved Sonic 1, 2 & 3

@topic.

the hardware shipment tables on this site are accuarte, but are no longer updated. If you look at the September 2000 shipment information, you'll see that the GB is 105m while the PS1 is at 75m

But surely the egg that the chicken was born from is a chicken egg

That's the point of the riddle.... many people will try to disprove it by saying there were eggs before the chicken evolved, but it is referring to chicken eggs, and thus depends on whether you consider a chicken egg to be the egg a chicken was born from or the egg a chicken lays. (ie if we were to have single generation evolving--- something that is not quite a chicken lays an egg that has a chicken inside, was that the first chicken egg or do we wait for this chicken to lay an egg)

It's obviously the egg.

I mean, what's more realistic - a fully grown duck suddenly becomming a chicken, or an egg being messed up genetically?

I think the latter is far more probable.

Except as I said above.... it then depends on what your view is on a chicken egg.

If the egg is messed up genetically and a chicken comes out of it, does that mean that it's egg was a chicken egg even though it wasn't a chicken that gave birth to it? or do we wait for the (genetic anomaly that is now a chicken) to lay an egg?

Miyamoto-sama created the chicken.

I'm wondering... Why are there no hardware shipments tracked after March of 2007?
