He also said that Tesla would "die" without him as its CEO, even though it's not a job he likes having.
"I rather hate it," Musk said, "and I would much prefer to spend my time on design and engineering, which is what intrinsically I like doing."
Design and engineering apparently fall under Musk's other job title: Technoking of Tesla.
The company filed paperwork in March formalizing the position.
Baron asked Musk whether Tesla's board vetted the Technoking title. Musk didn't answer directly, instead explaining that his sense of humor helps generate untold amounts of free publicity for the electric car maker.
"If we are entertaining people, they would write stories about us, and we don't have to spend on advertising, which would reduce the price of our cars," Musk said.
"I think I'm funny."
