Stan Pines

Stanford "Stan" Pines, better known as Grunkle Stan, is Mabel and Dipper's sly great-uncle. He runs the Mystery Shack, a tourist trap full of questionable oddities. When he's giving tours or sleeping on the couch, Dipper and Mabel are usually sneaking out to explore the town’s secrets, though Grunkle Stan may have his own mysterious secrets.

History
Sometime during the month of June, Stan's great niece and nephew (Mabel and Dipper) were sent from Piedmont, California to stay with him for the summer. Stan immediately puts them to work in his house-turned tourist trap, the Mystery Shack. Stan's other employees include Soos and Wendy Corduroy. At the end of "Tourist Trapped", it's revealed that he has a secret door behind the vending machine in his house.

When Grunkle Stan wants to take Dipper and Mabel to Lake Gravity Falls to bond with them, he states that the guys from the lodge won't go with Stan because they don't "like or trust him". Though he reveals in a way that he does love Dipper and Mabel a little, since he does make them fishing hats, meaning that he does want to spend time with them for once. Dipper and Mabel try to get away from Stan's fishing idea by going with Soos to catch the Gobblewonker so they can get $1,000. Stan gets upset that Dipper and Mabel would rather go on a monster hunt than go fishing with him, so he tries to find his own fishing buddies around the lake. This doesn't turn out right for Stan, since everyone just thinks of his jokes as annoying. Later when Dipper, Mabel and Soos return from their voyage, Dipper and Mabel asks if they can bond with Stan, feeling bad that they left him earlier. Stan accepts their request, and they all end up having quality family time Stan has been wanting for.

When the twins and Soos see a commercial for the physic 'Lil Gideon, Stan tells them that he is his arch enemy and has been nothing but trouble for him since he arrived in Gravity Falls. He also says they're not allowed to see Gideon's show, but Dipper and Mabel find a loophole and go anyway. Later, Stan learns that Mabel and Gideon are dating, and disapproves. He goes to talk to Gideon's dad, Bud Gleeful or Buddy Gleeful, about it, but he changes his mind when Bud says they can pool their profits. Stan even tells Mabel she has to marry Gideon. After Mabel breaks Gideon's amulet, Gideon forces his dad to call off the deal. Stan then steals a clown painting and yells, "Try and catch me, suckers!"

Grunkle Stan also has a very large crush on Lazy Susan, though he soon regrets asking her out in "Dipper vs. Manliness." He has a party at the Mystery Shack during "Double Dipper," so kids come there more often, and so that he rake in the cash from the children, since the admission to get out is $13 and on the flyer it says "Free?". Grunkle Stan despises Pioneer Day, and later gets trapped in a wooden stock for yelling at "Steve" a.k.a. "donkey boy or the mechanic". While Stan is locked up, Gideon throws tomatoes at his eyes, and he gets taunted by Pacifica Northwest. In "The Time Traveler's Pig", Grunkle Stan opens up the Mystery Fair to earn more cash, and rigged the Dunk Tank by making the target connected to the seat very stiff, causing Stan to not fall no matter how hard the people threw. When Dipper and Mabel time travel, the twins pass the Mystery Shack from which a younger Stan briefly emerges. Later, one of the members of the Time Paradox Avoidance Enforcement Squadron (Lolph) fires his blaster at the target, which causes Stan to fall off the seat and into the water, satisfying the crowd of people.

In Fight Fighters, Grunkle Stan was accused of ackin cray-cray by Mabel when he said he didn't own a ladder. It is then revealed that Grunkle Stan has a fear of heights. When he thinks he has conquered his fear, he did a cocky dance to confirm that he was cured.

In Little Dipper, a man is at Stan's door when Dipper, Mabel, and him were watching tv, he answers the door and thinks that the tax collector is here for him, so he runs and gets a bag of full of cash behind the painting that he stole from a restaurant.(Mystery Shack Mystery) Soon learning that it wasn't them and that they are the "Winning House Coupon Collector's Contest" and that they are there to give him $10,000,000, since his dream was to "possess money" had finally come true, so he signs. but Gideon comes out saying that he just signed the Mystery Shack to him, but on the paper he signs "SUCK A LEMON LITTLE MAN" instead. Throughout the episode Gideon tries taking the Mystery Shack away from Stan but ultimately fails. so when Gideon has Mabel and Dipper mini an in his possession he calls Stan saying that he has them and that he has to give up the Mystery Shack in order to get them back but Stan doesn't believe him so Gideon says that he would text Stan a picture of them, but Stan doesn't know what texting even is and ends up hanging up the phone. Though Gideon goes to the Shack to shrink Stan and take over the Shack, before Stan and Soos are setting up the mirror maze that is supposedly gonna bring him in cash, and that was Soos's idea that Stan is taking credit for. once Gideon gets into the Mystery Shack he finds Stan, but since Stan is in the maze Gideon can't find him but soon breaks every single mirror he sees and finds him. He corners Stan and tries to zap him, but meanwhile mini Mabel and Dipper start tickling him and says that he is a good enemy that maybe their rivalry has gone too far, so he "rolls" Gideon out of the shack.

Personality
Dipper and Mabel's great-uncle, Grunkle Stan, is a gruff, greedy and miserly salesman who has finally managed to set up his shop in a town with enough unsuspecting customers to sell worthless knickknacks. His flair for showmanship is oddly hypnotizing, and thus he is able to make money by peddling the bogus trinkets and baubles in his store. His work ethic is mainly driven by his desire to make money, so when he's not generating an income, he's usually at home watching television. Even though he sends the twins on unpredictable and outrageous errands, he always has their best interests at heart and loves them unconditionally. Meanwhile, when he isn't busy trying to make a quick buck from his unsuspecting customers, Grunkle Stan is guarding his own secret that might hold the key to unlocking the mystery of Gravity Falls.
