Two thousand years in the future, a blonde(ish) and average height(ish) girl waited for her destiny. She had been cryogenically frozen in the year 2016 in order to meet her true calling, which she had been born 2000 years too soon for.
In the year 4016, she was thawed in a secret underground hideout that was hidden beneath an ice cream factory. The people who took care of her for all those years cried when they first met her, having never heard her voice. Unfortunately the first thing that came out of her mouth was a burp, and the second was a swear word as she realized she was naked and was really not happy about it.
"I asked to be frozen in my sweatpants dammit!" She yelled, trying to cover herself under a plastic sheet.
"But ma'am, the fibres would have fused to your skin permanently." The poor girl in the lab coat stuttered.
"hmm," The scarcely covered woman pondered, "Permanent sweatpants eh? Let's do it, another twenty minutes be good enough to seal that in?"
"Yes, the fibres will fuse immediately."
"Excellent, let's do that first. That way, I will always be wearing sweatpants." She claimed back into the chamber and pulled the comfiest sweatpants she could find over her bare legs, securing them snugly but comfortably. If they were going to be on her forever she would need them to be on properly.
The lab coat girl set the timer for twenty minutes and watched through the glass door as the sweatpants fused to her skin. The reanimation process revealed that it had in fact worked, her sweatpants successfully fused to her legs.
"Excellent, now what is my mission? What have I waited for 2000 years to do?" The woman asked, admiring the sweatpants on her comfortable legs.
"Actually, your mission is to design the most comfortable sweatpants ever. However you need to be able to try them on. How will you do that with the sweatpants legs?"
"WHY DIDN'T YOU SAY THAT BEFORE YOU IMBECILE!"
"I'm sorry" the lab coat girl cried, "You were so sure of your decision."
"You know what, it's fine. You know what's more comfortable than sweatpants? Double Sweatpants. Let's get to work."
And so they began the journey of testing sweatpants for the remainder of her life, trying them on on top of her sweatpants-legs also allowing the lab coat girl to try them out on regular legs. They developed the most comfortable sweatpants and once they did, the lab coat girl showed her how to operate the machine so she could be forever in the most comfortable pants in the world, and when she came out of freezing she developed a machine that would infuse the old pants off of the woman and allow her to get the new pants on. So everyone lived happily in their sweatpants.
