In “Family Business,” a first-season “Dallas” episode, J.R. (Larry Hagman) visits Bobby (Patrick Duffy), who sits in his bed.
J.R.: You could have told me about the cancer.
BOBBY: Slipped my mind. I guess I was too busy trying to undo all the damage you caused.
J.R.: OK, I admit, I have lapses where I do wrong now and then.
BOBBY: No, J.R., your lapses aren’t when you do wrong. Your lapses are when you do right. Like the scorpion who said to the frog, “It’s just in my nature.”
J.R.: Well, you happy with your doctor? Because I’ve given a truckload of money to the UT medical school.
BOBBY: J.R., I love you. No matter what. You remember that.
J.R.: Well, my memory’s not what it used to be, either. You’re just going to have to keep telling me.
BOBBY: Nobody lives forever.
J.R.: Well, I’m not going to stand here and listen to you write your obituary. If you have something to say to me, you say it when they get that thing fixed in your head.
