So it's getting close to Christmas and Betty is excited because she wanted to take Jeff out to go shopping for stuff and she thought it was gonna be fun
"Come on Jeffy let's go"
"AW YEAZ WE'RE GOIN TA JC PENNY'S"
And they went there and then when they walked inside there was a huge commotion going on
They looked confused for a while and then shrugged and kept going
Then a random dude yelled to some one else across the hall
"Hurry up man we're gonna miss the big blowout sale at hot topic!"
Then they both for excited after they over heard the dude
"HOT TOPIC BLOWOUT SALE??? BETTY WE GOTTA GO CHECK IT OUT"
"YYYEEEEAAASSSSSS UNDERTALE AND KINGDOM HEARTS AND THE WORLD ENDS WITH YOU MERCH CRAP LET'S-A-GO"

So they freaked out for a while
Until they finally got a hold of themselves and they went inside

And then they started looking around
But then the shelves were full of little robot-looking dolls that the people were buying like crazy

It was the only thing they wanted to but which was weird because it wasn't even that cute

Then Jeff looks at the receptionist at the counter...

"...B-Betty..."
"Yes?"
"It's... It's...
*whisper* Kelsie Callous..."

Yep
There she was
Mrs. Long nose herself was smirking at the counter
"Heh heh... Soon I'll make a killing off those Endocrine emitting robots..."
Apparently she made the dolls give off Endocrine so the people would be gratified by them and but them by the dozen so she could get rich.
Then Betty whispered into Jeff's eat
"Ok here's the plan. You pretend to want to buy one and while she's distracted I'll turn off the power. Then we pitch all the dolls in the dark and high-tail them out of here into the furnace across the mall."
So Jeff grabs a doll
And starts acting goofy
And while Kelsie looks confused because he looks familiar the lights go off
And everyone starts FREAKING out
And then they get a shopping cart And put all the dolls in there and ran
...with Kelsie right behind them
When they looked back she was holding a little blaster gun
"Oh My Jeff! We GOTTA GO FASTER JEFFY!!!"
And then they crashed into a pillar in the middle of nowhere and the dolls all went flying

And the hit the floor And all broke and the Endocrine filled up the entire mall
That's when they decided to leave before they got trampled

Kelsie however was not so lucky.
"*step* OUCH WATCH WHERE YOU'RE GOING*trample* AUGH! I HATE THAT OBESE-ATRICE!!! *clobber*

Later that day...

They were at home watching "Santa Claus is comin' to town" (which is my favorite movie about him of all time) and Jeff had a question

"How come the Endocrine didn't affect us?"

"Well... It's probably because we're already happy. I have the world's most precious Jeffy... And you have the world's biggest fattest Betty. Ha ha!" *wink*

"*blush* actually I was going to assume most precious and most beautiful but I guess if That's what you th--"

"Jeffy shut up and kiss me already baby cakes"

And he did

The end
