Pinkie Pie was bouncing down the streets of Ponyville, beaming about the party she was mentally planning to celebrate the job offer she'd just received from the NBA. They'd offered her a billion cupcakes and a top-notch set of dentures for Gummi if she would lead a workshop teaching players how to bounce high enough to slam dunk without exerting any effort. Such an employment opportunity was a cause for festivities.
Without warning she was flipped upside down. "Oh! A twitch signal! Quadruple-ear-flop right-knee-twitch-double-blink-hair-twirl-kidney-failure-barrel-roll-moderate-back-ache? I haven't had that one in ages! Last time that combo came around was when there was an armed warhead filled with weapon-grade Poison-Joke powder headed straight for Ponyville-ha ha! Bioterrorism is a great prank! I have to go tell Twilight Sparkle!"
"Spike, if I start paying you more than 10 bronco-bucks a week then it'll cease to be an allowance and be counted as an actual salary, which means your chores would no longer be chores but would instead count as child labor. Experience puberty so you qualify for adolescence and we can talk again," Twilight Sparkle turned back to her books.
"PUBERTY!" Pinkie Pie exclaimed as she rocketed through Twilight's floor, filling the air with splinters as she hopped up onto Twilight Sparkle's desk and bouncing up and down in place. "What's that?"
"I uh...We'll have an explaining party for you when you're old enough..." Twilight Sparkle replied as Pinkie Pie's bouncing broke her ink well and sent ink spewing onto her face.
"OH DOKEYS-THE-LOKEYS! APARTYPARTYPARTYPARTY!" Pinkie Pie squealed so loudly Twilight's horn curled "I'm going to have to throw a party celebrating all the parties I'm gettting to party in recently! First the one celebrating my job offer from the NBA, then one celebrating the return of this wierd combo-twitch I had this afternoon and now one for explaining PUBERTY!"
"Wierd combo-twitch?" Twilight Sparkle turned her ink-covered head to the side "Which one is this?"
"Oh, just a quadruple-ear-flop right-knee-twitch-double-blink-hair-twirl-kidney-failure-barrel-roll-moderate-back-ache."
"Huh, don't have record of that one yet," Twilight Sparkle magicked down the observation notebook where she'd been orderly documenting the meaning of all of Pinkie's twitches and started writing. "...double-blink-hair-twirl-kidney-failure...and what does this one mean?"
"Just that an armed missile packed with weapon-grade Poison Joke powder is rocketing towards Ponyville as we speak."
"...armed missile full of weapon-grade Poison-Joke-WAIT WHAT!" Twilight Sparkle seized Pinkie Pie by the shoulders "ARE YOU MAKING THIS UP"
"Nope! It's the Apple-Jack-Honest-Truth! Cross my heart and hope to fly. Stick a cupcake in my eye!"
"WE'RE ALL CERTAINLY DOOMED!"
"HOORAY! That means I can all max out my credit cards throwing the best Doomsday Party ever without worrying about the consequences!"
"DOOMED!"
"Not that I've ever really worried about consequences. My cholesterol level is probably higher than Equestria's national deficit, but that isn't stopping me from eating this life size frosting-version of the Lincoln Memorial!"
