Most people remember this episode because of Jackie's phone call with her hard-of-hearing aunt.
"Dad's DEAD," she yells as she tries to tell her aunt that her and Roseanne's father died. However, what's often missed from this episode is the revelation that their father was cruel and abusive.
Roseanne in particular is forced to come to terms with her complicated feelings about her father, the love mixed with resentment, and the aspects of her combative personality that she may have gotten from him.
