Of course the simple explanation for Argonian boobs is that the devs are too lazy to adapt all of the clothes and armor for them to be flat chested, so all of the females ever have the same body model.
Why do Platypus lay eggs if they are mammals?

Yeah. But funny thing is, real life is so much more intricate and odd. Some real life reptiles can actually breath under water. Its not through their mouths and they don't have gills. Care to know where?

I doubt half the people here even know what the word "cloaca" means.
