Key takeaways from Elon Musk's "Saturday Night Live" appearance

The big picture: In his opening monologue, Musk noted O.J. Simpson hosted "SNL" twice "and he killed it."

• He also joked about smoking marijuana during a video interview with Joe Rogan and his son's name, "X Æ A-12" ("It's pronounced cat running across keyboard.")
• Musk also said he's the first person with Asperger's syndrome to host the show and joked "or at least the first to admit it." However, Dan Aykroyd, who has said he has mild Asperger's syndrome, hosted "SNL" in 2003, Deadline notes.

Of note: The billionaire's mother, Maye Musk, appeared alongside him, after the show opened with the cast's moms, in a nod to Sunday being Mother's Day.

• She said she's "excited" for her Mother's Day gift. "I just hope it's not Dogecoin," she added, in reference to the cryptocurrency Musk has praised.
• "It is," he shot back, smiling.

For the record: In an "SNL" first, the show was broadcast in full to over 100 countries — including Canada, the U.K., Brazil, India, Russia, South Africa, Australia and New Zealand.
