Pete Davidson mocked comedian Louis C.K. after he made fun of survivors of the Parkland, Fla., school shooting in a controversial leaked comedy set.

Davidson, performing in Boston on Monday night, poked fun at C.K. in his first live show since posting a troubling note to Instagram late last month, E News reported.

The “Saturday Night Live” cast member relayed an anecdote about his tattoos, describing how Alan Rickman, known for playing the character Severus Snape in the “Harry Potter” movie series, died the day after Davidson got ink relating to the franchise.

“Then I got a Willy Wonka tattoo. Next day — Gene Wilder dies,” Davidson said of the 1971 film’s star.

“Now I'm like, alright, that's a coincidence, that's weird,” he continued. “So I'm thinking of getting a tattoo of Louis C.K., what do you guys think?"

Davidson joked that the punchline used to be about actor Aziz Ansari but said he changed it because “Aziz has been nice to me recently.”

C.K. has faced a new wave of backlash in recent days for a performance in which he ridiculed the survivors of the February mass shooting at Marjory Stoneman Douglas High School that left 17 people dead. The teenage survivors have since become vocal gun control advocates.

“They testify in front of Congress, these kids? What are they doing?” the comedian says during his comedy set, according to audio posted on social media Sunday by comedy writer Jack Allison.

“You’re young, you should be crazy, you should be unhinged, not in a suit saying 'I’m here to tell you' — F--- you, ” C.K. continued.

It is unclear when and where the comedy set occurred, according to Forbes. 

The comedian apparently also went after people who use gender neutral pronouns “they/them” and children with developmental disabilities.

C.K. has been attempting to make a comeback in stand-up comedy after admitting that sexual misconduct allegations against him that resurfaced in 2017 were true.

He performed his first comedy set since admitting to the accusations in August at the Comedy Cellar in New York.

Davidson’s stand-up routine in Boston was his first since posting a troubling message on Instagram. He wrote in a since-deleted post, “I don’t want to be on this earth anymore.”

The 25-year-old comic has opened up before about his mental health struggles, including his battle with borderline personality disorder.
