*Above pic* "I'm a papa~! Who da mare~? Aw yeaaah~!"



*Stares from Twilight, Fluttershy, Pinkie and Rarity*



"What?"



"Ummm, Rainbow Dash? You can't be a papa. You're the completely wrong gender."



"But Applejack's the mama! Besides, it's cooler to be called the 'daddy', and Applejack always wanted to be 'mommy' anyway."



*More stares*



*Twilight speaks up* "Okay, nopony else is going to ask it, but we're all thinking it: How?"
