John Oliver came for Jay Leno and his request that "a bit of civility" come back to late night, using Leno's old Monica Lewinsky jokes as ammunition.

Oliver called out Leno in a NSFW segment on public shaming on Sunday's "Last Week Tonight."

The late night host brought up the spectacle that surrounded Lewinsky, the former White House intern who engaged in a sexual relationship with President Bill Clinton.

"It is impossible to overstate just how globally famous Monica and private details of her life became," Oliver told viewers. "The media obsessed over every angle of her story from tabloid stories... to cartoons... to endless late night comedy jokes."

Oliver admitted his "hands are not clean here either" bringing up an anniversary piece done by "The Daily Show."

"It's gross!" he exclaimed of his complicity. "Many comedians have since publicly expressed regret about things they said, although one who hasn’t, and who's among the most relentless, was Jay Leno."

David Letterman admitted on an episode of the "Late Show" in 2014 that he felt "bad about my role in helping push the humiliation to the point of suffocation." Bill Maher said he "felt guilty" for his Lewinsky jokes on a 2014 episode of "Real Time with Bill Maher," according to the Chicago Tribune and Politico.

Oliver showed a montage of some of Leno's cracks about the former intern Sunday.

"One million samples of DNA," Leno told a late night audience in one clip. "They said this is the largest collection of DNA in the world, not counting Monica Lewinsky's closet."

The Hollywood Reporter and Today reported in 2014 the findings of a study from the Center for Media and Public Affairs at George Mason University which said in 22 years on "The Tonight Show," Leno targeted Lewinsky 454 times.

"Those jokes have not dated well in any sense of the word," Oliver said. "And they're pretty rough, especially coming from a guy who just this week complained about late night TV saying that he'd like to see 'a bit of civility come back.'

Oliver then resurfaced another one of Leno's old jokes, with a lewd book title refererncing Lewinsky.

"If that’s what he means by civility, may I offer my new book: 'Oh, the Places You Can Go (expletive) Yourself, Jay Leno!’" Oliver continued. "Look how civil I'm being. Look how civil this is!"

Leno expressed a desire for civility while appearing on the third hour of "Today," last week.

“Everyone has to know your politics,” Leno said, reflecting on late night today. "I kind of used (Johnny Carson's) model, people couldn't figure out (my politics)... and I would get hate mail from both sides equally, and I thought, ‘Well that’s fabulous, that’s exactly what I want.’

"But, when people see you as one-sided, it just makes it tough," he added.

“Now it’s all very serious... I’d just like to see a bit of civility come back to it," said Leno.

Explaining the motto when he was at the helm, he said: "The theory when we did the show was, you just watched the news, we'll make fun of the news, get your mind off the news. Well, now people just want to be on the news all the time, so you just have one subject. It's the same topic every night which makes it very hard."
