For years now I've had the image of this scene in my mind, annoyed that I can't place it. It could be a series as well, I guess.. Saw this when I was much much younger but can't remember exactly when.

Very simply a woman (I think it's a woman, pretty sure) stands in the kitchen, drinks what I assume I remember as alcohol and she places her hand in some kind of waffle iron or toaster oven and presses it down squishing her hand. Then takes another sip of her drink without having much of a reaction while her hand is still in the toaster/waffle thingie
