PRANK 1: EDITH'S EXPERIMENT

Edith, aged 7, was easily the most mischievous of Steve Gru's three daughters. Always up to something, always having to cover up her mahogany skirt-clad rear end. (Rather adorable, really...)

So it was no surprise when Dr. Nefario hit her with this question when she wandered into the lab one day:

"What're ya doing here, Pinky?"

'Pinky'. Edith couldn't tell if Uncle Nefario gave her and her sisters these nicknames out of love or if he straight-up couldn't remember their real names. 'Maybe both,' she thought.

"Whaddaya mean, what am I doing?" Edith said, smiling and batting her eyelashes innocently. "Can't a girl walk into her Dad's lab without getting asked a gazillion questions?"

Dr. Nefario waved her off airily.

"Eh, whatever," he grunted, continuing his work on the Truth Serum Gun (TSG) Gru had ordered, not noticing Edith sneaking along the shelf behind him. "Just don't play with anything. Gru got you girls that toy box for a reason."

While Nefario still had his back turned, Edith grabbed a stepstool and poured a bottle of Sir Pranxter's Exploding Science Juice in the inventor's Truth Serum, then ran back into the living room, where Margo was reading a book and Agnes was having a tea party with Fred and Phil, respectively.

A smirk grew on Edith's face as she began the countdown. "1...2...3!"

KABOOM!

Smoke erupted from the lab down below, and Dr. Nefario screamed, making both of Edith's sisters jump.

Edith burst into raucous laughter as a dazed and black-faced Nefario appeared in the entrance tube, swaying slightly.

"Sorry, Books," the inventor slurred, addressing Margo. "Ya can't have that Prince o' yours, I'm smoked."

And he collapsed on the hardwood floor, unconscious. Agnes, looking concerned, passed her Uncle a teacup.

Edith, still giggling, looked triumphant.

"BOOYA! You just got EDITH'D, Uncle Nefario!" she cried.

Her older sister raised an eyebrow.

"'Edith'd'? Really?"

"I know, AWESOME, isn't it?" Edith said with another giggle.

Her mission accomplished, she turned on her heel.

"I'm gonna go play with my planes. Later!"

And she skipped upstairs to their room, at the same moment Gru entered the living room, demanding an explanation for the ruckus.

Margo rolled her eyes.

"Edith's on her pranking spree again."

Agnes gasped and hid under the party blanket.

"No, no! I don't wanna be pranked! Daddy, help me!"

Gru looked at the 5-year-old for a moment, then turned back to Margo.

"Vut do you mean, 'pranking spree'?" he asked as he picked up Agnes, who clutched his neck tightly.

"She goes through this phase where she pulls as many pranks as she can for an entire month," Margo replied, returning to her book.

"Vell, she eez only 7," Gru said with a weak chuckle. "How many pranks could a 7-year-old possibly pull?"

"You'll see," Margo said darkly.
