If Mabel earns one day's profit in three days, he'll let her be boss for the rest of the summer and do an "apology dance" that Mabel choreographed.
If Stan returns from his three days vacation with more money than Mabel could earn, Mabel will have to wear a "Loser" t-shirt all summer.
After Mabel begins acting aggressive like Stan and Dipper using underhanded tactics, they got a net worth of $1 (having to deduct the damages done by the Gremloblin). However, Stan lost all the money he made in a 'double or nothing segment.' The word he failed to guess was please, the word he mocked that wouldn't earn money. Mabel and everyone else agree that Mabel will not run the Shack as she realizes the responsibility. Nevertheless, he still does the apology dance. Funnier still, he has to repeat it until he gets it right, takign at least 31 tries
Break the Cutie: Mabel just does not get a break in this episode until she starts becoming Stan.
Hoist by His Own Petard: Stan mocked the idea of using the word "please" for anything, and that he'd never be able to get money using the word. His greed, and not knowing that word is why he lost the bet he so smugly made with Mabel.
Dipper defeated the Gremloblin using a mirror to make him project its own worst nightmare.
Sarcasm-Blind: Mabel, when Grunkle Stan says to "tell it to the complaints department" and then holds up a trash can.
Mabel: I'm going to write them such a letter.
Taking Advantage of Generosity: Mabel offered Wendy a hand to improve her working situation, Wendy took the whole arm; even after seeing the shack ruined, she was about to flee out of work until Monday with the excuse of a headache instead of helping until Mabel snapped and turned all Stan on her butt.
The World Is Not Ready: When Dipper captured a real monster to show in the shack, tourists didn't buy it over the fake attractions; Dipper proves them wrong by letting the monster Mind Rape them and they were needed to be taken into the hospital.
Vomit Indiscretion Shot: Subverted when we briefly see the tourists from Stan's point of view. They're all walking, talking wallets, and one of them vomits coins.
