"You have committed crime which must lead to a death sentence!"
   "No! Please! I'm sorry- I'll fix it!"
    "We do 𝗻𝗼𝘁 take excuses!"
    "But it's not an ex-"

Stan led the two kids down to the basement. He opened the large door, and walked in. Dipper and Mabel gave each other a look, then also walked in.

There was a large cover on something. "What's that?" Mabel asked.

"That.. that is what I've been working on," Stan replied, as he whipped off the cover, making the twins jump.

"Ta-da!" He introduced. Dipper and Mabel gasped. "It's.. a car.." Dipper said.

"Yes, but not just any car!" Stan stated, opening the door, which went upwards. He got in. "C'mon!"

D and M climbed in, and they looked around in awe. Stan was in the driver's seat, Dipper was in the middle, and Mabel was on the other side. All at the front.

"You built this?" Mabel asked.
  "Yup!"
  "What makes you think it's illegal?" Dipper questioned, turning his head to Stan.

"Well.. it sounds a bit far-fetched.. but.."
   "Just tell us."
   "It can teleport to the past, and maybe the future. I doubt that though."

Mabel's eyes lit up in awe. Dipper opened his mouth for a gasp, but it never came.

"How? That's impossible." Dipper stated.
"Wanna give it a go at midnight?"
"YES!"
"Why midnight? Does it mean something?"

"Yeah, the clock has to strike midnight in order for it to work. Also because there's less cops around."

Mabel was standing next to car. Dipper was ON the car. Stan was on the big clock (don't ask how he got there), on the city's Town Hall, setting up a wire.

Dipper was holding the end of the wire, and was attaching it to a pole on the car. The wire had to attach to the cable line.

"If we get arrested, this is your fault!" Dipper yelled at Stan, sweating.
   "I know!"

Mabel was leaning on the car, waiting to do something. "Grandpa Stan?"
    "What?"
    "Can I do something?"
    "Erm.. get in the car."

Mabel grunted. She wanted to help. "Whatever, at least I won't be guilty if the cops come."

23:57

After lots of hard work, they finally got everything ready. "Ok, guys? We ready?" Stan asked, getting into the car.

Dipper and Mabel buckled in "yup!"
Stan did the same. "Ok, let's go!" He yelled, firing up the engine.

It made a weird noise, when suddenly the car started rushing along at an incredible speed.

The twins clutched to each other "Is this gonna work?" Mabel asked, worried.

"I know it is. It's gotta, I've seen someone do it."
"That was in a movie, wasn't it?"
"Erm... m..maybe.."

Dipper was about to speak, when suddenly the top of the car was starting to light on fire, along with the road, making a horrible noise.

Then, the clock struck 12. 𝗗𝗼𝗻𝗴..𝗗𝗼𝗻𝗴..𝗗𝗼𝗻𝗴..𝗗𝗼𝗻𝗴...

They were waiting for the 12th strike, with the car edging closer and closer to a tree.

...𝗗𝗼𝗻𝗴..𝗗𝗼𝗻𝗴..𝗗𝗼𝗻𝗴..𝗗𝗼𝗻𝗴..

"QUICKLY!" Dipper yelled.

...𝗗𝗼𝗻𝗴..𝗗𝗼𝗻𝗴..𝗗𝗼𝗻𝗴..

The car was about to hit the tree..

..𝗗𝗼𝗻𝗴

𝘽𝙊𝙊𝙈!

A small explosion happened, leaving some smoke behind. There was fire on the road, where the car tracks had been.

Three cops ran around the corner, guns in there hands, waiting for the smoke to clear.

When it had cleared, there was...

𝙉𝙤𝙩𝙝𝙞𝙣𝙜.

"Wh..what?" A cop said.

Yes, indeed there was nothing. The car had gone, taking Stan, Dipper and Mabel with it.

"𝘼𝙃𝙃𝙃𝙃𝙃𝙃𝙃𝙃𝙃𝙃𝙃𝙃𝙃𝙃𝙃𝙃𝙃!" They all screamed. They all closed their eyes in fright, and opening them to..

The 17th century?

"What?" Dipper asked. They had landed in front of a sign labelled '16th May 1647'
"We're in 1647? This is a joke, right?" Mabel asked, chuckling a bit at the end.

Stan couldn't believe it himself either. "This can't be right. How did-"
  "Dude! We should probably leave! Isn't a car like this gonna look weird? It looks weird in our timeline, anyway!" Dipper explained.

"Never mind the car, what about us?" Mabel asked.
"We need the car! How are we supposed to travel back?"

Dipper and Stan got out the car, Mabel following after. They looked around.

"Oh.. guys.." Dipper gulped. They looked on top of the car, and smoke was coming off. "I think we broke it.."

"WHAT?" Mabel and Stan jinxed.
