Yonderland / Radar

Since Yonderland is aimed at an older audience than Horrible Histories, it makes sense they'd have even more raunchy stuff.

The Chosen Mum

Wizard Bradley

Negatus, relaxing in his bath, sighs and claims that being an evil overlord must be the worst job in the world. A small creature holding a toothbrush then emerges from the water between his legs and begs to differ. The clincher?
Negatus: Oh, shut up and do the other one.
This, when Debbie asks the Wizard for a potion to cure her sick husband:
Debbie: "Actually, there is something you can do for me. Let's go back to your place!"
Wizard Bradley: "Oh! Uh...well, I'm very flattered, Debbie, but it's been a while...and I'm a little rusty with, ah, technique..." *hand gestures*
There's another one in the 1970s flashback.
Wizard Bradley: It even looks like a wand!

Reformation

The monks of Old John, by the rules of their Order, must always tell the strictest truth. Debbie's not convinced.
Debbie: "That's rubbish, everyone can lie. 'I'm washing my hair'... um, 'It was good for me too'..."
Negatus is suffering from some sort of rash on his "Gentlemen's-excuse-me" which could translate to a sexually transmitted infection. This also puts a new spin on The Crone in the news segment trailer claiming that Negatus threatened to give her a disease...,
Baynton's monk asks Debbie to come back to his place and promises he'd call her in the morning.

The Ultimate Prize

Philip of Woolworth, champion knight, attempts some suave flirting with Debbie:
"My face is leaving in five minutes..." For those who don't know the joke in its entirety, the punchline is, "Be on it."
"My career's over, I'm going to have to sell my ass. I really love that donkey."

Closing the Portal

Jim Howick's pink haired masseuse offers to irrigate Debbie's colon.
When Debbie emerges from her spa treatment looking refreshed and rejuvenated, Elf says she looks great...and then follows it up with an impressed "Hubba, hubba!" and honking hand gestures.
Elf tells Debbie that Ennythingos is home to Yonderland's "equivalent of the clap, so just...don't."

The Idiot King

Nick the stick is woken up from a dream that, from what he says, involved a woman and a bottle of linseed oil. Given that linseed oil is often rubbed on wood, and Nick is completely made of wood, it's not a stretch to imagine what his dream was about.
This line from the king's song to Debbie, followed by returning with a hammer and smashing the radar to bits.
Bernard: "What's a royal seed without a fertile field to germinate? (suggestive raised eyebrow)"
A female peasant, after getting a dress from Debbie, says "C'mon, let's go down t'the lake" to her male companion (Willbond), who responds with a very telling "Yes!".

The Heart of the Sun

Everything Negatus' "minion of the month" Kendall says:
Kendall: "You've been a naughty little girl, haven't you?"
Kendall says he had to spank his machine. The machine he constantly caresses, fondles, strokes and calls a woman.
When one of the ninnies realises that the person he thought was his wife was actually her brother, we get this exchange:
Ninny: Oh god. What have I done?
Nick the Stick: What haven't you done.
Debbie's husband gets rather... excited about Debbie offering to make a tape with him until she clarifies it's a showtape.
Pete seduces Debbie at the end of the episode with his Sun God hat.

Dirty Ernie

During Debbie's birthday party (when it isn't her birthday), Vice Elder Flowers (Farnaby) enters as the stripper.
After Havelock is once again thwarted when trying to propose to Ms. Fanshaw, he finally suggests they just "live in sin", much to her delight.

The Winging Detective

Elf’s last line in the episode ‘I love a happy ending’ whilest having a massage is a massive one, considering what ‘happy ending’ can mean in certain massage parlours.

A Vicious Circle

Debbie says that her husband once shaved his downstairs area to resemble Australia, which he then corrects “it was supposed to be a heart!”
“oh we’ve all got demons mate. My wife used to make me dress up as a beaut-“
Debbie calls Nick ‘Stickhead’ (lovingly, but still)
Ellis Of Woolworth is heavily hinted to be gay or ace “all I used to do was try to be brave, which is a lie, and flirt with girls which is a-“

The Last Fahl

This episode is almost entirely penis jokes, the two most blatant examples being the suggestive silhouettes scene and the fact that Negatus' logo looks like a cock-and-balls
Early on, Jeff the demon gets "power vacuum" mixed up with "vacuum cleaner", mentioning he got stuck in one once. Negatus remembers he "told [him] not to put it in there".

Series 3

They get a lot of mileage from the fact that Cuddly Dick is named, well, Dick.
