(I apologise in advance)
Rainbow Dash felt strangely happy. Not ecstatic, just a calm happiness in her heart and a song in her head. A song she both hated and loved. She loved it because it was so simple and catchy, and she hated it because it was so simple and catchy.
It was parading around her head. The tune repeating itself on a continuous loop for days now, but she didn’t care, it made her feel good.
She walked thought the town centre, her head bobbing along to the tune as she walked. She shut her eyes and the tune became louder. She could feel a bounce in her step appearing.
She started to quietly hum the song.
It grew louder in her mind, and she never realised but it made her break out into a strut in time with the rhythm and her humming became audible to those close by.
Her walk turned to mild dancing. Her shoulders swaggered from side to side with each step as she fell into a pattern of two steps forward and one step back.
If she opened her eyes she would feel such embarrassment it would be impossible to live it down. Everypony was staring at her, wondering what put her in such a good mood.
She slipped up.
“Mahna mahna!” she said loudly as she lost control of herself.
Her eyes shot open and she moved a hoof to cover her mouth. She saw the masses of Pony staring at her. Her cheeks reddened and she tried to hide herself away, shrinking back and smiling awkwardly.
Then she heard something that surprised her.
“Do Doo Be-do-do,” came the soft reply from above her.
Rainbow looked up. It was Fluttershy, of all Ponies, who replied from the small cloud she was lying on. She didn’t believe it at first; it was far too outlandish for the meek Pegasus.
“Mahna mahna?” Rainbow tested, eyeing the yellow Pegasus to see if she would do it again.
Fluttershy flew down next to her.
“Do Do-do Doo,” she replied with a smile.
“Mahna mahna.”
“Do doo Be-do-do, Be-do-do, Be-do-do, Be-do-do-doodle Do Do Do-doo Do!”
There was a brief pause.
“Mahna mahna,” Rainbow sang happily, breaking out into a dance-walk.
“Do Doo Be-do-do,” Fluttershy sang back, with her hooves hitting the ground with each syllable as she moved to catch up Rainbow.
“Mahna mahna!” Twilight interjected suddenly, shaking her rump in time with the music she sang.
Rainbow and Fluttershy looked to the Unicorn with mild surprise and sang back without breaking step, “Do do-do doo.”
“Mahna mahna!” Pinkie Pie shouted as she jumped beside Rainbow, hitting her flank playfully as she landed.
The other three looked over with smiles.
“Do doo Be-do-do, Be-do-do, Be-do-do, Be-do-do-doodle Do Do Do-doo Do!”
They stopped in front of Applejack’s cart, with patient smiles as they waited for her.
Applejack looked embarrassed to be near them at that moment as they were distracting her customers. In the end she shrugged her shoulders and threw off her apron.
“Mahna mahna,” she sang as she jumped in line. The group began walking off with a small dance in their steps.
“Do Doo Be-do Doo.”
“Mahna mahna!” Rainbow sang.
“Do Do-do Doo.”
“Mahna mahna,” Twilight shouted, almost breaking up with giggles.
They stepped between each of their hooves as they sang the next line.
“Do doo Be-do-do, Be-do-do, Be-do-do, Be-do-do-doodle Do Do Do-doo Do!”
They froze. They were at a loss. They didn’t know who could start them off again. They almost gave up and stopped, but then they were saved.
“Mahna mahna!” sang Rarity as she trotted up between the group.
Her friends flashed her a quick smile; they were slightly surprised to see her joining in but they didn’t let that faze them.
“Do Doo Be-do Doo!” they replied to their new leader.
“Mahna mahna!” she sang elegantly.
“Do Do-do Doo.”
Rarity spun around to face her friends. “Mahna mahna!”
They paired up with their matching race and tapped their hooves with each sound they sang.
“Do doo Be-do-do, Be-do-do, Be-do-do, Be-do-do-doodle Do Do Do-doo Do!”
They froze, their eyes locked onto the ones they were facing.
Rainbow grew a devious smile which she showed to her friends. They all knew what she was thinking.
They stood up on the hind legs and loudly announced into the town.
“MAHNA MAHNA!”
The town replied in immaculate chorus.
“Do Doo Be-do Doo!” They all tapped their hooves on the hard cobble stone ground and swayed in time with the music.
Rainbow and her friends looked to each other with satisfied smiles on their faces. They began to trot down the street with great exaggeration.
“Mahna mahna,” they sang in unison.
“Do Do-do Doo!” the town sang back. In sounded wonderful, the whole town singing in key and creating brilliant harmonies.
“Mahna mahna!”
“Do doo Be-do-do, Be-do-do, Be-do-do, Be-do-do-doodle Do Do Do-doo Do!”
It was at this point that Twilight realised something. Nopony knew how this song ended. But luckily she saw they were approaching this edge of town.
“Mahna mahna!”
“Do Doo Be-do Doo.”
“Mahna mahna.”
“Do Do-do Doo.”
Twilight could hear the town getting quieter as her and her friends became closer to leaving the town.
“Mahna mahna!”
“Do doo Be-do-do, Be-do-do, Be-do-do, Be-do-do-doodle Do Do Do-doo Do!”
The town had become a quiet mumble as the six Ponies crested the hill and disappeared from view.
The town started humming the tune quietly, feeling like it shouldn’t have ended yet.
Rainbow and her friends returned to the top o the hill for the big finale.
“MAHNA MAHNA!” they shouted at the tops of their voices, signalling the end of the song.
The town stomped their hooves on the ground in applause, with some light cheering and whistling going on.
The Ponies on the hill bowed to their audience and left the scene.
Celestia and Luna had been observing Ponyville at that precise moment through a complex array of telescopes and magic, creating a holographic screen depicting the town with full 10.1 surround sound.
“Well,” Luna started. “It wasn’t as extravagant as the usual musical numbers they do, but still no less entertaining.”
Celestia chuckled in agreement. “You’re quite right there. But the question is.” She leaned closer to her sister. “What exactly IS a mahna mahna?”
“The question is; who cares?”
The two regal sisters broke out into a hearty laughter.
