Is imitation the sincerest form of flattery? Not for Elon Musk, at least when it comes to "Saturday Night Live."

The Tesla CEO, who hosted "SNL" in 2021, slammed the show on social media Sunday, the day after Dana Carvey debuted an impression of him.

" 'SNL' has been dying slowly for years, as they become increasingly out of touch with reality," Musk wrote in response to a clip of the segment.

"Their last-ditch effort to cheat the equal airtime requirements and prop up Kamala before the election only helped sink her campaign further," he added, referring to Vice President Kamala Harris' cameo on the show before Election Day.

After Harris' appearance, NBC filed a notice with the Federal Communications Commission and said it would provide Republican nominee Donald Trump equal time. The former president addressed viewers during a NASCAR Cup playoff race that aired on the network the following day.

In another X post, Musk criticized Carvey's performance, writing, "Dana Carvey just sounds like Dana Carvey." He also said "they are so mad that" Trump won the election and agreed with a user who claimed more people have seen the sketch on X than on "SNL."

'SNL' stars jokingly support Trump:Dana Carvey plays Elon Musk

In the Nov. 9 episode's cold open, the cast of "SNL" jokingly claimed to have been supporters of Trump all along in order to avoid being on his list of enemies when he begins his second term.

Near the end of the sketch, Kenan Thompson sarcastically said that in a worst case scenario, "We can all go to Mars with the other man that we love and trust," Musk.

Carvey then entered as the billionaire, wearing a black "Make America Great Again" hat. He jumped around the stage and put his fists in the air, declaring, "I run the country now. America's going to be like one of my rockets: They're super-cool and super-fun, but there's a slight chance it could blow up and everybody dies."

Musk hosted "SNL" in 2021, and the decision to have him on drew some backlash. In a review at the time, NPR's Eric Deggans said the appearance was only "so-so" and that it was "disappointing" creator Lorne Michaels "once again allowed a problematic public figure to burnish his image by hosting the show, only to deliver an episode unworthy of all the hype and hot takes." Trump also hosted "SNL" in 2015 amid his run for president.

Musk has previously said on X that "SNL" has "become so woke" and is "so rarely funny these (days)."

The SpaceX founder wasn't the first person to criticize a sketch poking fun at them on "SNL" this season.

In October, Liam Gallagher slammed the show for a "Weekend Update" segment where the Oasis frontman, played by Sarah Sherman, bickered with his brother Noel (James Austin Johnson). On X, Gallagher asked if "they (are) meant to be comedians" and called Sherman's impression of him "excruciating."
