Colgate's Nation

Twilight Sparkle was on her way to the market for more carrots when she noticed something nailed to the library's bark. She turned to face it with mild irritation, knowing that piercing the tree's surface harmed it. However, she did not bother to read the add. She only saw Colgate's face. She smiled. She was glad that Colgate was going up the employment ladder and decided for some unknown reason to go congratulate her. After a brisk trot she found her reading a book in the park. As she looked up from her novel, she was startled by the smiling facial features of Twilight and dropped her book in shock. " Oh! I'm quite sorry, Colgate. I just wanted to say how great it is you've gotten that new job. You must be so proud!" Twilight spoke. Colgate nodded happily and flashed a pearly-white grin as she waved goodbye and went back to reading her book. Twilight found it quicker to teleport home then walk, after all, the park was across town. The carrot cart had rolled away anyway.  To her shock, she found a collection of ponies surrounding the library that hadn't been there before. She tried politely asking what the trouble was but no one would answer!  Finally she resorted to shouting out " WHAT IN EQUESTRIA ARE YOU ALL LOOKING AT!?!"  everyone turned and pointed a hoof to the poster. Twilight had never read the message but now she could see it. " If you don't care about dental hygiene, you're a disgrace to your country!" Twilight turned around to face them. " oh, calm down. It's just a catchphrase. A silly, dumb marketing jingle that shouldn't even arouse a sniffle from you. carry on now. Go back to being normal, healthy, productive equestrians." She said. Bit by bit, the crowd cleared all except for Applejack, Rainbow Dash, and Spike. " Well, Sanitary's my middle name! I haven't got a cavity once and I eat freaking rocks!" boasted Spike, puffing out his chest. " PIFFFF! Who needs brushing your teeth? The apple is nature's toothbrush." Said Applejack, munching on a golden delicious. " EWWWW!!! That's disgusting! Everyone knows that the wind in your face is more refreshing with minty-fresh breath." piped up Rainbow Dash.  The 3 walked away bickering as Twilight walked inside and slammed the door behind her, tearing the poster down with the force. It flew up and away over the breeze.
