"Have you ever seen the president naked?" Jimmy Kimmel asks while grilling former White House press secretary.

Sean Spicer made his late-night debut Wednesday night on "Jimmy Kimmel Live!" to spill on his time in the White House, now that he's "free."

"He survived one of the worst jobs ever and is free at last to speak about it," Jimmy Kimmel said to introduce Donald Trump's former press secretary, who was actually surprised by the audience's positive reaction when he stepped on stage.

The pair chatted about the true size of the president's inauguration, Trump's constant use of Twitter, Melissa McCarthy's SNL impersonation and The Mooch. Read on below for all the best bits.

Inauguration crowd size

Kimmel questioned Spicer's claim that Trump's inauguration "was the largest audience to ever witness an inauguration, period, both in person and around the globe," since the media published statistics proving otherwise.

Spicer said he was just following orders.

"There's a lot of us that wanted to be focused on his agenda, what he spoke about, his inaugural address, but he's president," Spicer said. "He made a decision."

Has He Seen Trump Naked?

"Why is he so concerned with size?" asked Kimmel. "Have you ever seen the president naked?"

"I have not," Spicer replied.

Trump's tweets

Spicer said Trump never consulted him about what he posted on Twitter, so Spicer had to settle for Twitter alerts, and then prepared for damage control.

Spicer also told Kimmel that the president rarely watched any of his press conferences, but when he did, he received feedback.

"It's my job to speak on his behalf so if you're not speaking in the way that he wants, obviously he wanted to make sure he corrected that."

"Saturday Night Live"

Looking back, Spicer does think McCarthy's impression of him is "kind of funny," then confirmed what we all knew: Trump hates the comedy sketch program.

"I don't think [Trump] found as much humor in it as others," he said.

The Mooch

Spicer told Kimmel that contrary to some reports, he actually did get along with Anthony Scaramucci, who briefly held the job of White House communications director. Still, Spicer did say he saw some red flags.

"Anthony has been very successful in business. He's made a ton of money, but I just didn't feel as though he had the qualifications or the background to work in the communications office."
