This is really what happens when Princess Peach invites Mario to eat with her.
{At Peach's Castle}
Peach: Hey Mario I'm glad you came.
Mario: I don't give a fuck about you! Where's the real Peach I'm looking for?!
Peach: (Sighs) Here she is...
Mario: OH YEAH PEACHY YOUR BACK!!!!!! (Licks frosting off of the cake)
Peach: (Sighs) I don't even know why I'm here anymore...
Luigi: Will he be alright?
Peach: Nope... not to me probulay to him he's fine.
Mario: I'M FINE!!!! YOUR THE ONE WHO'S NOT FINE. (Eats cake)
Peach: Says the one who acts like a person on drugs when seeing my cake. (Crosses arms)
