Saw this on a fluff Prompt and decided to give it a poke. Not sure if this is worth a full story or not, but I just churned this out. Started with the first line.
"Can you open this jar for me?"
Wandering all the way to her bedroom, Bruce provides a jar with a lid that was stuck tight. Earning a flat look from his petite girlfriend, as she leaned back from her chair where she had been bent over a project of hers. Interrupting her typing with his out of the blue, question.
"...Really?"
"Yes, Really."
"-And you came all the way to my room, while I am working to ask?"
"Well, it was that or bother Daphne in the living room, and I want to play favorites."
Sighing, Velma got up from her desk to give him another look. Making her way around the bed to stare up at him, dwarfing her and the tiny pickle jar in his hands. Analyzing the situation, and figuring out the solution to what he was presenting her. Taking in a breath and sharply snorting it out, Velma shook her head and wandered back to her desk. Going through her drawer, Velma was searching for something.
Bruce wasn't sure what she was up to, but was curious anyway, leaning himself to try to peer around the bed to see what she was trying to find.
Making a small noise of victory, Velma resurfaced from her scavenging and had brought out a roll of black tape. It was over an inch thick in width, and still had a decent amount of tape still left. Rolling it in circles around her fingers skillfully, she made her way back around to where Bruce was standing. Looking up with a shake of her head, she put out her other hand and wiggled her fingers at him. Demanding the stubborn jar from his grasp, without removing it from his hands without permission.
"Give."
With a smile pulling his face to the side, Bruce was eager to see what she had in mind. Offering the offending container to her. Curious on what his girlfriend would do next.
Loud pulling tape sounds came as she placed the jar on her bed and got to work. Placing a few strategic pieces of tape upon the top of the lid, she made herself a handle. She then turned to Bruce and brought up both of his hands, leaving a gap for the jar to then be placed. She the retrieved the glassware and moved to fit it in his grasp. Waiting for him to close his hands around it, before she made her move.
Gripping the tape handle she had created, Velma effortlessly tugged the top off with a loud POP! Using the leverage she created for herself, to get the lid off with no problem. She then peeled off the tape and returned the lid back to Bruce.
"Couldn't you have just unscrewed it?" Bruce asked, taking the lid back from her hands.
"Last time I tried, I crushed the jar in my hands. So, this is a cleaner method. Why couldn't you do it?" She shot right back at him, though without her normal sting. Since she could afford a quick breather before she returned back to her work. And well, he had come to her for help. She didn't want to admit it, but she liked being the preferred choice.
"Alfred banned me from opening jars... I got creative in a bad way, and ending with a similar result."
