Along with the supernatural and paranormal occurrences, it seems that the radar seems to be a little sketchy as well. Considering some people who worked on certainshows worked on Gravity Falls, this isn't that surprising.
The statue of Sasquatch wearing underwear is titled "Sascrotch".
The gnomes' plan for Mabel to marry all of them. She's just twelve, and it's mentioned that there's at least a thousand of them. You do the math.
"I thought you kids were playing Spin the Bottle with Soos!"
After Dipper asks her to imagine what she could do with five hundred dollars, Mabel has an Imagine Spot in which she buys a human-sized hamster ball. She then fantasizes about rolling up next to two boys in their car and hitting on them, saying "You can look, but you can't touch." before rolling away.
Wax William Shakespeare: Uhh...there once was a dude from Kentucky-
Mabel: Nope! (throws head into fire)
"The Hand That Rocks the Mabel"
When Gideon's father offers Stan Colombian coffee, Stan replies that he once got arrested there. Make of that what you will.
The Smile Dip pretty obviously makes Mabel high. It's not even subtle...
"Dipper vs. Manliness"
The whole episode is pretty much about Dipper wanting chest hair. Not to mention that, at one point, one of the manotaurs said he has fists for nipples. He even said the word "nipples". And then we get a close-up.
This was edited out of the episode's re-runs for a while, but they eventually put it back. Nipple-fists for all!
How this line got past the censors, the world will never know...
Dipper: So what if I don't have hair in certain places?!
Also, one of the Manotaurs is named Pubeator.
Instead of genitals, the Multibear's crotches have bear heads. note A slang term for penis is "the second head."
After Mabel gets her Eureka moment on how to get Grunkle Stan and Lazy Susan together...
Mabel: Grunkle Stan, come with me to the diner! And leave your pants at home! Stan: With pleasure!
Dipper wants to prove his manliness on one of those grip-strength measuring machines.
Dipper: Time to man-handle this... man-handle.
There's a rather dark moment when the old Manotaur is eaten. And unlike the Summerween episode he doesn't come back, so he's probably dead.
Dipper scraps a name he chose for his clone named "Tyrone".
Dipper: I shall call you "Number 2"! Tyrone: Definitely not...
Apparently it is legal for the people of Gravity Falls to marry woodpeckers. The implications of a man marrying a woodpecker (and on a Disney show, no less!) are...something.
"If you're watching this, then you are one of the eight people in these United States with clearance to view this information. In fact, I myself will be shot as soon as the filming is complete. (looks offscreen) What? No? Hah! Well, that's a relief!"
At the the end, Trembley tells the twins about the time George Washington chased him around and spanked him for three hours.
"Bottom line, George Washington was a jerk."
"The Time-Traveler's Pig"
Mabel and Dipper get their hands on a time machine. When discussing what points in time to go to, Mabel has this suggestion:
Mabel: We should get two dodos and force them to make out!
Also in that episode Robbie wants to show Wendy his new tight pants. And then he thrusts.
When Dipper and Mabel wind up in pioneer days, they meet a pregnant woman surrounded by a bunch of kids. Her name? "Fertillia".
It should be pointed out that the last few words that Mabel has Rumble read off the cards are...
The Trickster actually eats one child on-screen He is shown as alive when the Trickster dies, however.
"I've been twamatized!"
Near the end, Stan readies for his bath and his bathrobe drops to the floor. Two kids to walk in on him, scream in horror, and run away. It's shown a few seconds later that he was still wearing boxers, but the implication couldn't have been clearer.
On a poster for Tambry's party, there is a warning that says nothing better end up online. What exactly do the kids do at these parties...?
The poster also originally said "Bottles will be spun", but Standards and Practice disagreed with a Spin the Bottle reference (despite 'Spin the Bottle' actually being said out loud in an earlier episode), so it was replaced with "Not S&P approved".
Soos kills The Trickster by chest-bursting out of it and eating its heart.
Although she does it for the blackmail value, which isn't much better...
Also the gay subtext with the two cops again. One scene of them rubbing suntan lotion on each other, and Blubs's line, "With you, every day is a dream" as he places his hand tenderly on the deputy's shoulder....
Stan telling Mabel (in Dipper's body) about "the birds and the bees."
Stan: It all begins with this little fella, the pituitary gland. He may be little but he has big plans!
Stan: And now you know where babies come from!
(Mabel as) Dipper: Goodbye, childhood.
Not to mention the whole reason he gives The Talk is because he thinks Dipper is spying on the girls' sleepover. He even says "Oh, you're at that creepy age where you like to spy on girls." Or words to that effect.
The age-inappropriate romance novels Grenda brings to the sleepover.
After the first sleepover. Mabel wakes up with "Party Gurl" written on her forehead, Candy is duct taped to the ceiling, and Grenda comes out of a small closet, covered with kiss-shaped lipstick marks, and says:
Grenda: I don't know what I was kissing in there, but I have no regrets!
Soos, after being burned multiple times, says the last one started to feel good.
Old Man McGucket, after switching bodies with Candy, starts dancing around and saying "I regained my innocence!"
Just the name of the band "Sev'ral Timez", made clearer from one of their lyrics;
"How many times am I gonna love ya? Several times!"
Robbie asks Wendy to join him at Lookout Point.
And, to Robbie's "surprise", they ended up alone, in a car, up there.
After telling Dipper an anecdote from the '70s, Stan notes that his memories get a little "hallucination-y" at the end.
He's also rather fixated on his ex-girlfriend's hot pants.
The guy from the Boy Band who gets very into kissing a tree during The Tag.
"Land Before Swine"
"Bros before dinos!"note A parody of the phrase "bros before hoes"
Blubs:*puts hand on Durland's shoulder* "The time we spend together is treasure enough."
Cue shared blissful grin.
"Stan-Vac: It sucks more than anything! *beat* Gotta work on that."
The blood-splattered pages in the journal for Bill.
Soos: This is Stan's mind? I figured there'd be a lot more hot old ladies.
This episode features a child summoning a demon, even referring to him as such.
The British Dog Man asks Soos, "Who's crike for a stick in the pudding?"
Dipper's nose was bleeding when a robot version of Gideon knocked him onto the edge of a cliff and into a rock, marking the first instance of realnote fake blood has been shown previously blood in the show.
Not only do we see Jeff the gnome bathingin squirrels, but after tossing Mabel and Dipper out of the shack he calls more over to jump inhis pants. Who ever was censoring this episode was in a coma.
Especially when one considers that it's a straight up fist fight with no fantastic elements like super powers. (Besides the fact that they're in a robot.) Usually when that happens it's A Very Special Episode where the kids learn not to fight, but here Dipper straight up punching someone saved the day.
A despondent Grunkle Stan orders "your strongest, most expired cider." When cider ferments it becomes alcoholic.
"Dipper's Guide to the Unexplained"
Dipper tried to spy on Stan in the shower to see his tattoo.
After Dipper discovered that tiny alien-like creatures were actually controlling the left-sided man, they all committed suicide. Right there on the screen.
Even worse, one tries to get out of it, saying "I can't do this man, I have a family". Then we watch as his boss tells him he knew what he signed up for, and shoves the pill in his mouth.
Soos asks the all knowing mail-box what his dream woman would be. It spits out a picture of a body builder babe and when Soos sees it he says "Whoa, hot tamales! Save that one for the archives!" as he tucks it into his shirt.
"Mabel's Guide To Life"
In the "Mabel's Guide To Fashion" short, Old Man McGuckett can be spitting something, possibly tobacco, into a bucket.
The Stinger at the credits, shown both agents apparently about to pull their guns.
A cryptogram on the pages for the "leprechorn" translates to "Kill me please".
"Into the Bunker"
Dipper is over at Wendy's house watching a cheesy movie and lays down on her bed, leading to this bit of awkward:
Wendy: Dude, you're laying on my bra.
When Dipper and Wendy get trapped in the main laboratory, the decontamination protocol activates and washes them and knocks them into each other, which causes Dipper's face to land right in the middle of Wendy's chest. Afterwards, you can see Dipper's eyes looking right at Wendy's chest.
Soos opens a weapons cabinet. We see several weapons in there, such as a flintlock, an axe, some dynamite, and funnily enough an actual shotgun.
"The Golf War"
Robbie spray-paints "wieners" on the wall of a castle, then makes "lewd hand gestures" at the King of Mini-Golf from just off-screen.
The Lilliputtians actually try to KILL Pacifica, and explicitly say it.
While waiting for the kids in the car, Stan ends up putting on smooth jazz and reclining his seat. Then Soos (with his shirt off) leans back as well and tells his boss "Sure are a lotta stars out tonight..." Stan mutters "This is gettin' weird" and promptly gets out of the car.
One of the Miner Lilliputtians, Big Henry, ends up sacrificing his life by carrying Mabel's ball through a gas leak, all for the honor of his fellow Miners.
What book is Mabel holding in the library? "Ready Baby: How Babies Are Made".
While Bill is possessing Dipper's body, he goes down to the kitchen and starts slamming Dipper's arm in a kitchen drawer. What's that shown stabbed into his arm when he takes it out? It's a bunch of forks. And the fork wounds might be bleeding, although it's hard to tell.
"Soos and the Real Girl"
When Soos' grandma says he needs to get a girlfriend before he "goes to heaven to sing with the angels," Soos adds, "And Grandpa!"...to which his grandma responds that his grandpa wouldn't be there. Think on that for a sec...
Her eyes even look down to the ground when saying that!
