Much to fans' delight, comedian Steve Martin made a surprise cameo on this week's "Saturday Night Live" to channel Roger Stone, a former campaign adviser to President Donald Trump who was arrested Friday.

In Saturday's cold open, cast member Alex Moffat played Fox News host Tucker Carlson, who tried to drum up sympathy for Martin's Stone.

"Mr. Stone, you've had a harrowing past 36 hours," said Moffat's Carlson. "Your home was raided. You were arrested and charged with seven felony counts, including lying to Congress."

"It was four counts!" interjected Martin, imitating the 66-year-old Stone.

"But the indictment says seven," Moffat's Carlson said.

"OK, I'm lying. Honestly, I think I'm the happiest I've ever been in my life," the fake Stone said. "I mean seven felonies – one, two – I can't even count that high. How cool is that?"

Moffat's Carlson then tried to steer "Stone" into saying he is a "feeble old man."

"Oh, yeah, right, the pity thing ... I'm just a poor, helpless old man. I'm 66. I'm almost as old as Sting," Martin-as-Stone quipped.

He continued: "The whole experience was so harrowing, and afterwards, I could only manage one radio interview, and a speech from the steps of the courthouse, and two appearances on television. It's horrible!"

Martin's Stone also complained that his legal battles have left him "broke."

"Now, no one will buy my books," he said.

"Well, why will no one buy your books?" Moffat's Carlson asked.

"Because they're bad!" the fake Stone replied.

He added that he was seeking donations online.

"I've set up a donation page based on a phrase people have been yelling everywhere at me, called, 'Hey, Roger, go fund yourself,'" said Martin-as-Stone.

"Carlson" then tried to wrap up the interview, saying, "Well, thank you for your time, Mr. Stone."

"Pardon me," Martin's Stone said.

"I said, 'Thank you,'" said Moffat's Carlson.

"Oh, no, that wasn't a question," Martin-as-Stone said. "I was saying that to the president: Pardon me!"
