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.

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.
