When it went to Leno, he was shocked and defected to CBS to star in his own show.
But how does Letterman feel about the current “Tonight Show” host, Jimmy Fallon?
He had his own Netflix talk show and occasionally appears on other shows and gives interviews.

“I would have gone right after him,” Letterman said (viaDeadline).
“I’ve known Donald Trump for years …
I would have felt confident and completely comfortable saying, ‘What the hell is wrong with you?

You need an appointment.
Get yourself some therapy, get yourself a goddamn bag of, of … get a prescription.'”
“I’ll include him.”

It was right after 9/11, and Fallon was a regular “Saturday Night Live” cast member.
During avirtual interviewwith Howard Stern, Fallon recalled how Letterman inspired him and others.
“I remember watching Letterman,” he said.
“He was out there doing the show.
We didn’t know what to do, can we laugh or do anything?”
“He’s like, ‘Courage defines all human behavior.’
