It's like they are testing how much they can get away with.

Even little girls' shows aren't above sending in a few stealth fighters once in a while.

In "Applebuck Season", Applejack says "Are you saying my mouth is making promises my legs can't keep?"
In "Bridle Gossip", after Appljack has been minituarized, Spike refers to her as 'Appleteeny', a pun on 'Appletini', or 'Apple Martini', a drink made from apple juice or cider and vodka (though Applejack is ALREADY a term for a kind of concentrated hard cider made from apples).
"Look Before You Sleep" features a book called Slumber 101: All You've Ever Wanted to Know About Slumber Parties (But Were Afraid to Ask), referring to the widely known sex guide Everything You Always Wanted to Know About Sex (But Were Afraid to Ask).
In "Feeling Pinkie Keen", Twilight has to rush to check on Fluttershy, and she puts Spike atop her by ramming him with her head. Thankfully, her horn stays a bit to the side. However, later in the episode, she has to pull the same maneuver to rescue him from a swamp, and her horn is nowhere to be seen as she races with him atop her head...while he has a shocked expression and his limbs splayed out, upper body rocking around, yet lower body firmly stuck in place.
A little over halfway through "A Dog and Pony Show," there's the Diamond Dogs' gleeful expressions of I Have You Now, My Pretty with Rarity acting like a scared little filly. Her line "Whatever do you want from me?" does not help matters.
In "Owl's Well that Ends Well", after Spike falls asleep with his head in a half-empty punch bowl, Pinkie jokes about the punch being "spiked".
In "The Mysterious Mare Do Well", Applejack calls one of her hind legs "Kicks Mc Gee", which is derived from the nickname "Tits Mc Gee" for women with large breasts.
In "Secret of My Excess", where Spike is going through what can only be described as "dragon puberty", what is the most common description Twilight provides for his behavior?

Twilight: He's getting kind of... grabby.

In "Putting Your Hoof Down", Fluttershy dismisses Pinkie Pie and Rarity's interests by saying nopony else gives a flying feather about them.
- There are other almost-swearing moments, like Rainbow Dash shouting "Oh, horse apples!" when she realizes she's fallen behind in the race in "Fall Weather Friends," and Twilight angrily asking "Who in the hoof is Princess Mi Amore Cadenza?" in "A Canterlot Wedding."
  - The "horse-apples" comment is especially fitting, if you happen to know about "road apples".
- Examining each character's use of these "almost-swears", Applejack is surprisingly the most foul-mouthed of the six, with Rainbow Dash just falling behind.
- Fluttershy uses her hoof to flip the bird. ^[1]
In "Hurricane Fluttershy", they slipped in a reference to steroid use and a certain one of its side effects with a white Pegasus boasting bulging muscles and rather tiny wings.
In the Cold Open for "The Super Speedy Cider Squeezy 6000", Rainbow Dash barges straight into Fluttershy's bedroom to wake her up, and rips the covers off. Fluttershy's reaction? She blushes and covers up her chest with her forelegs.
In "Ponyville Confidential", one of the stories printed in the paper was Fluttershy's tail extension, which, judging from the reactions, is treated as an Equestrian equivalent of breast implants.
- There's also Pinkie's "party animal problem," the picture of which shows her dancing in a punch bowl while wearing a lampshade. She breaks down crying admitting that it's true.
- And here's Sweetie Belle in...something that looks like a showgirl's outfit.
And in the S2 season finale, we round out the inappropriate humor roster by having Spike, who has been chosen to host Shining Armor's bachelor party, ask the main six just what one would consist of. The girls are too busy giggling to give any sort of answer.
As noted elsewhere on the wiki, the Changelings' modus operandi resembles that of succubi.
In Apple Family Reunion, Applejack is worried about the reunion, and her little sister Apple Bloom comes into her room to help her relax. The two then lay back on the bed with frazzled manes (which of course was used as the thumbnail for Hasbro's official clip). After that, Apple Bloom falls asleep on Applejack's bed, and AJ responds by pulling the covers over her, then putting her hooves on her butt and admiring her a moment before the scene ends without indicating where AJ then slept.

↑ Interestingly, a horse's hoof is a vestigial middle finger. So she is flipping the bird.
