Spicer on infamous press briefing about inauguration size: 'I don't think it was probably the best start'

"I don't think it was probably the best start," Spicer said of his 1st briefing.

"If I knew I'd get that kind of applause I would have left earlier," Spicer said to Kimmel, in reference to the roaring applause he received when he walked on the ABC show's stage.

Asked Kimmel, "Is it weird for you to be getting these types of applause?”

In a nod to his predominantly Democrat environs, Spicer shot back, "Yeah, especially in California."

In his six months as press secretary, Spicer garnered a reputation for verbal flubs and tense exchanges with journalists in the briefing room. In his first appearance on the job, the press secretary lambasted press coverage of Trump's inauguration and decried images showing sparse crowds on the National Mall.

And Kimmel took the opportunity to rib Spicer about that first press briefing.

"You are charged with going in front of the press and saying the inauguration crowd is the biggest crowd ever," Kimmel said.

Acknowledging that Kimmel was poking fun at the claim, Spicer said, "Yes, I'm aware of that. I appreciate the reminder of how it went down."

Responded Spicer, acknowledging how his ill-fitting suit was panned on the Twittersphere, “You know, if it was up to me I probably would have worn a different suit ... I thought I was going in on a Saturday morning to set up my office."

Kimmel asked if that first press briefing in particular was responsible for casting a shadow on his stint as press secretary.

"When you brought that crowd size thing out, you like opened this terrible Pandora's Box," Kimmel said. "Do you think that is what got you off to kind of a bad start with the press corp?"

Spicer shot back, "I don’t think it was probably the best start."

And one question that Kimmel couldn't refrain from asking -- considering it has provided fodder for many opening monologue jokes -- was, "Why is [Trump] so concerned with size. Have you ever seen the president naked?"

"I have not," Spicer said.

Earlier Wednesday, the Institute of Politics at Harvard's John F. Kennedy School of Government announced Spicer would be would be joining the program as a visiting fellow for the 2017-18 academic year.
