Knock, knock. Who’s there? Elon Musk.
And the typically chucklesome cast of “Saturday Night Live” is not laughing.
Giggles turned to groans for some members of the “SNL” ensemble Saturday when NBC announced that Musk, 49, will helm their sketch comedy show as host alongside musical guest Miley Cyrus on May 8.
The contentious Tesla CEO will be the first nonactor or nonathlete to host “Saturday Night Live” since Donald Trump spearheaded the satirical sketches in 2015.
Musk tauntingly confirmed his upcoming emcee gig tweeting: “Let’s find out just how live ‘Saturday Night Live’ really is.”
The polarizing tech tycoon — boasting a net worth of approximately $179 billion — punctuated his cryptic post with the grinning devil emoji to let his 52 million Twitter followers know he means business.
But “Saturday Night Live” quipster Bowen Yang seemed to have hoped that Musk’s social-media memo was nothing more than a bad joke.
“What the f – – k does this even mean,” Yang, 30, questioned in an Instagram Story post attached to a screenshot of the SpaceX pioneer’s tweet.
Fellow “SNL” jokester Aidy Bryant echoed Yang’s concerns about Musk — hailed the third richest person in the world, according to Forbes’ real-time billionaire billboard — and his forthcoming term as master of ceremonies.
Bryant, 33, reposted a tweet from Bernie Sanders as a thinly veiled dart aimed at Musk which read: “The 50 wealthiest people in America today own more wealth than the bottom half of our people.”
“Let me repeat that, because it is almost too absurd to believe: the 50 wealthiest people in this country own more wealth than some 165 MILLION Americans. That is a moral obscenity,” the cyber barb continued.
“Saturday Night Live” writer-turned-trouper Andrew Dismukes, 25, joined the jibing, saying on Instagram, “Only CEO I wanna do sketch with is Cher-E Oteri” — a reference to the former “SNL” veteran.
Yang, Bryant and Dismukes’ social-media shafts have since been deleted.
Spokespeople for the comedians did not immediately respond to The Post’s request for comment.
Reps for “Saturday Night Live” were also not available to comment.
But “SNL’s” online audience eagerly took to Twitter, airing their grievances about Musk’s impending appearance.
The shady shots to Musk from “SNL” stars and habitués alike likely stems from the COVID-19 misinformation he touted at the onset of the pandemic.
The engineering magnate digitally downplayed the deadly virus, calling panic induced by the outbreak “dumb” in March 2020.
He also wrongly predicted that there would be “close to zero new cases” by the end of last April.
That same month, he demanded an end to pandemic closures.
Musk also came under fire for a foreboding Twitter missive in which he threatened to revoke stock options from Tesla employees if they moved to unionize.
But the National Labor Relations Board forced him to remove the tweet.
Most recently, he nonchalantly said that a “bunch of people will probably die” during his forthcoming Mars mission.
