"Get ready..." Twilight Sparkle said. She and all five of her friends were standing around a sundial, watching it intently. According to the shadows, it was very nearly 11:30. Every week, at exactly this day at exactly that time, some sort of shenanigans seemed to happen, and Twilight wasn't having it any longer.
The shadow moved into position, marking the half hour. It clicked into place as neatly as you like.
"Now!" Twilight exclaimed, and all six mares tensed up for the inevitable. They looked around expectantly, in all directions.
There was no super villain rampaging through town, and the Cutie Mark Crusaders were watching a movie at the local theater instead of running around being ignorant. The map-like table in Twilight's Castle was silent, not beckoning them off to some grand adventure, nor were their cutie mark ringtones vibrating.
There was absolutely nothing.
"I don't get it," Twilight said slowly. "Something always happens! Always!"
"Well, maybe it ain't happened yet," Applejack said. "Could use a week off. Ah got chores t'do."
"No!" Twilight exclaimed. "Somepony somewhere needs to learn a lesson! And it's our job to make sure that it's learned properly!"
"I really don't think that's how this works," Rainbow Dash said.
"I don't care!" Twilight said. "If I can't find a problem to solve, I'll make one!"
Rainbow Dash and Fluttershy exchanged a glance. Whoa. Deja Vu.
Twilight didn't hear her, she was off already, and beginning a supposedly necessary check of every building in town. Carousel Boutique had not burned down, Sugarcube Corner did not need any last minute packages delivered. Discord had not turned the local water supply into fruit punch, 'But thank you for the idea, dear Twilight,' he'd said.
Applejack reluctantly allowed Twilight to search the farm, and there was nothing amiss there either. The apple trees were blooming with springtime arousal, the fields were in the process of being plowed, a new barn was halfway through to be completed. There was no musical number or fanfare in the building process this time.
Fluttershy was brought to tears as Twilight rounded on her during the search of her home, as she was doing an emergency headcount of all her animals under the alicorn's insistence. A pair of rabbits, who had scurried off somewhere to do what rabbits are known for doing were unable to be found, and when Fluttershy sat in her own living room with tears streaming from her eyes, Rainbow Dash finally kicked Twilight out.
Twilight grew increasingly frantic as the afternoon wore on, and still nothing happened. There were no calls to distant lands by diamond dog tribes, nor any previously unheard of family members making sudden, unexpected appearances. By early evening she was actually breaking into closed businesses, convinced that perhaps the owners were perhaps being held hostage in their own shops and needing her help.
By the time the local constable came to take her down to the cool-down tank, Twilight was in hysterics.
"Saturday morning! IT'S ALWAYS SATURDAY MORNING!"
She was thrown in a holding cell next to a bright blue mare in a straight jacket. The mare's left eye rolled back up into her head, showing only the whites, and the right eye fixed on her, a wildly erratic grin on her face.
"Heeeeeeeeeey," the mare fidgeted in her restraints. "What're you in for?"
