Man, I love this. Charles Martinet must have had a field day with this one, it's so funny listening to his over-the-top delivery. I especially like how he pronounces "New Super Mario Bros." And whenever he says "a little bit shy, like a little baby mushroom, aw."
Because I suspected there was some fancy generate-audio going on, I tried typing in two unusual names, but it said it didn't know how to pronounce them. Geez, it doesn't even know how to pronounce "Bowser" or "Yoshi". So let's hope your name and whoever you're sending it to are common names.
Just checked the field for types you can choose from for how you're related to the recipient, and I noticed "Mario" and "Love Bunny". Something about "love bunny" is hilarious to me, but I've never heard of someone being another's Mario. I've heard of being someone's Yoko Ono, but not Mario.
