The game show parody has been a fundamental building block of “Saturday Night Live” since time immemorial, from one-off bits like “Jackie Rogers Jr.’s $100,000 Jackpot Wad” to long-running sendups of “Celebrity Jeopardy!”  and “Family Feud.” 

The format achieved a kind of Platonic ideal on this weekend’s episode of “S.N.L.,” which featured a satirical game show that seemed perfectly calibrated for the current moment.  It was called “What Even Matters Anymore?”  and starred an increasingly unraveling M.C. played by the evening’s guest host, Jessica Chastain. 

Ms. Chastain explained it as “the show where I tell you something our president did or said, and you have to tell me: Does it even matter anymore?”
