Okay, so all people across the internet consider that Mario has a live outside of rescuing the Mushroom Kingdom. This life includes having sexual intercourse with Peach, Daisy, and Rosalina, and who knows who else? That is not the case.
The reason why sex doesn't exist in the Mushroom Kingdom is because during Yoshi's Island, the stork gets kidnapped and so does Luigi, so Mario and Yoshi rescue him. But during the credits, the stork takes baby Mario and Luigi to their parents, and it says "they meet their parents for the first time", so that means not only have Mario and Luigi not met their parents, but that humans are an evolution of birds since the stork delivers babies around the world. So therefore, humans are birds. The end.
