(Dipper and Mabel's Bedroom)

Dipper, Mabel, Wendy and Soos were in the middle of the bedroom, playing the classic game of Truth or Dare.

"Alright, Soos, truth or dare?" Dipper asked.

"Truth!" Soos quickly responded with excitement.

"Between Mabel and Wendy, which would you marry in the future?"

The girls went "Ooooh!" in excitement and turned to Soos.

Soos scanned both girls, who tried to hold back their laughter as he checked them, and after a while he finally made his choice. "Well, I would marry...Wendy!" Soos proudly stated while pointing at the teenager.

Everybody started to laugh out loud and the girls fell to the ground upon hearing the man's answer. They continued to laugh as the boys stopped and they got up.

"Oh, Soos, you scallywag!" Wendy said in the middle of her laughter. "Okay, who is next?"

"That's Dipper." Mabel answered as she pointed at her brother. "Well, what is it going to be, dear brother?"

"Well everybody has picked truth so far, so I'm going to pick dare."

Mabel took some time to figure out the perfect dare, getting a mischievous look on her face on she got an idea.

"Then I dare you to..." before she finished, Mabel took out from behind her back a stick with a rubber spider hanging on a thread. "Scare Grunkle Stan with this rubber spider!"

Laughter yet again filled the room and everybody fell, clutching their stomachs as they laughed like hyenas.

(Stan's Bedroom)

The old man was on his bed and fast asleep, making it the perfect chance for the group to execute the prank. Soos slowly opened the door, with a slight creak being heard as it opened and made Stan start to wake up. Soos stopped the door and, with time, Stan fell asleep again.

With the door open, Dipper grabbed the stick with the rubber spider from Mabel and silently sneaked inside, the rest peeking from the sideways and holding back their laughter. Dipper made sure to not step on anything that could wake up Stan, and when he got near his bed, he gave the rest a thumbs up.

Smiling, Dipper slowly moved the spider closer and closer to Stan as Soos and Mabel watched anxiously and Wendy took out her cell phone. She started recording the event as Dipper waved the spider across Stan's nose, who slowly woke up and was met with the spider looking straight at him!

"Oh look, a rubber spider." Stan remarked.

Stan's response was not what was expected, to say the least. Dipper stood there with an angry look on his face, thinking of something and saying "boo" while waving the fake spider.

This time, Stan freaked out.

"Rubber Spider Ghost! It's the ghost of a rubber spider!" Stan screamed as he jumped off his bed and ran away. "Run for your lives!"

Dipper returned to the team and laughed with the rest as they walked back to the twins' bedroom. "I got it all recorded!" Wendy exclaimed...and then looked a bit worried. "Oops."

"Why oops?" Mabel asked.

"I think I sent it to my friends."

The team stopped and turned to Wendy, except Soos who heard his phone ring and reached for it. "What?!" the twins exclaimed in horror. "Are you serious?"

"Haha! Hey, Wendy, this video you sent me is amazing!" Soos laughed some more before showing the rest the video. "It's just like that moment ago when Dipper scared Stan with the rubber spider!"

The trio watched the entire video and then turned to the man with deadpan looks. "Soos, it is the event in question." Dipper matter-of-factly told Soos.

"Oh...well I guess we should better run for it then."

"Why?" Dipper asked.

And then the ground shook.

"DIPPEEEEEERRRR!"

"Okay, that answers my question. RUN!"

The quartet got up and ran as Stan quickly got up and chased them with a chainsaw. "Get back here!" Stan demanded.

The End
