Adult Hey Arnold Jokes That Probably Went Over Your Head

You may remember Hey Arnold for Stoop Kid, Helga’s unrequited love, or, of course, the main character’s unforgettable football head. You laughed along as the gang navigated the sticky situations that come up in middle school. But you probably didn’t catch all of the in the show. Maybe you noticed your parents giggling mysteriously at certain moments while you obliviously smiled along with Harold or Grandpa. Well, they were probably laughing at one of the many dirty jokes in the cartoon. Check out these list of in Hey Arnold to find out what you were missing the whole time. You’ll never look at cartoons the same way again.

Helga’s Love for Arnold Went a Little Too Far
We know Helga had a secret thing for Arnold, but it seemed to go a little far when she wrote in her journal, “Arnold, you make my girlhood tremble.” How that made it into a children’s cartoon, we may never know. In this same episode, Helga happily watches Arnold undress.
Helga’s Mom Was an Alcoholic
It wasn’t a single distinct moment that revealed this, instead it was the sum total of her actions and behaviors. Helga’s mom slurred her words, made “smoothies,” dozed off in random places, had her license revoked, and was once required to do community service. That last part sounds a whole like the punishment for a DUI.
The Sausage King
In the season six episode called “The Eating Contest,” there was a sign that said “try my sausage,” and pointed to an alley. This adult joke manages to be bold and subtle at the same time, but surely the writers knew what they were doing.
The Substitute Arnold Had a Crush on Had an Interesting Name
Voiced by Julia Louis-Dreyfus, Miss Felter was a substitute teacher whom Arnold had a crush on. Many speculate now that the name Felter was intended to sound like the phrase “felt her.” 
Grandpa’s Face Was Shaped Like a Penis
That’s just an obvious observation that you likely wouldn’t have realized as a child. Now, looking back, it’s nearly impossible to look at him without noticing the phallic shape of his face.
