Grandpa Subtly Revealed That He Used to Smoke Weed

On season three episode “Arnold’s Thanksgiving,” after Helga and Arnold leave a dinner, you could see something... interesting happening in the window. What exactly is it? Well, it appeared to be some type of inappropriate act happening in plain view, though it was actually supposed to be people arguing in the kitchen. Still, surely those responsible for drawing that knew what the positioning looked like.
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.
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.
