“Lorne [Michaels] was like a dog with a bone,” Carvey recalled.

“He just wanted me to come out anyway.”

That only enhanced Michaels' enthusiasm.

“We collaborated the rest of the week, and they were just cool.

They let me really do the Biden I wanted to do.”

And by the way, the fact of the matter is,'” he explained.

“So I ad-libbed it at read-through.

Carvey’s apparent improvisation surprised some of his less-seasoned collaborators.

“The current cast members, they’re all adorable people,” he said.

“They’re young and everything.

They’re like, ‘I didn’t know you could ad-lib at read-through!'”

Carvey also said he considered throwing more unexpected pop culture references into his rambles as Biden.

“And then I had him go, ‘Yabba dabba dabba doo!'”

I like ‘I can’t believe it’s not butter’ better.”

Carvey will return for more Biden material throughoutSNL’s 50th season.
