That '70s Show (1998)

Season 1: Episode 23

Red's mother Bernice has once again managed to make everyone miserable during one of her visits. While driving his grandmother home, Eric lashes out and tells her that it wouldn't kill her to be nice once in a while. Bernice promptly drops dead, leaving Eric to think he killed her. The entire Forman family (including Laurie and Red's brother Marty) comes together for her funeral while Eric gets drunk at a bar with the guys.
