Grand Duke: The Prince, sire, says he'll marry none but the girl who fits this slipper.
King: He said that, did he? A-ha, we've got him!
Grand Duke: But sire, this slipper could fit any number of girls!
King: That's his problem. He's given his word; we'll hold him to it!
Pinkie Pie: Rarity, your glass slipper! Now your prince is sure to find you!
(Rarity shrieks at the thought of seeing Prince Blueblood again and smashes the slipper with her hoof)
