Tomorrow and Tomorrow and Tomorrow — Kurt Vonnegut

The Schwartz family, headed by 172-year-old Harold ("Gramps"), lives in a three-room New York City apartment located in what once was southern Connecticut. Gramps' grandson Louis, his wife Emerald, and 22 other descendants are crowded into the space, perpetually jockeying for Gramps' favor. Gramps gets the best food and the only private bedroom, and controls everyone's life by constantly revising his will to disinherit anyone who earns his dislike. Emerald thinks about killing Gramps by diluting his Anti-Gerasone, but Louis talks her out of it. An offhand remark by him prompts Gramps to disinherit the couple and exile them to the worst sleeping space in the apartment. Louis then catches another family member diluting Gramps' Anti-Gerasone; fearing Gramps' reaction to such a scheme, he tries to empty the bottle and refill it with the full-strength mixture. He breaks the bottle and is caught by Gramps, who only tells him to clean up the mess. The next day, the family finds Gramps' bed empty, with a note informing them that he is dead and a newly rewritten will that bequeaths his estate to his descendants without dividing it.
