Elon Musk is the founder and CEO of Tesla Motors and SpaceX. He appears in the Season Eighteen episode, 'Handicar', where he participates in Wacky Races, driving his Tesla D car. He also appears in Season Twenty episodes 'Members Only', 'Not Funny', and 'The End of Serialization as We Know It', in which he makes a guest appearance, voicing himself. After having the announcement of his new Tesla D car overshadowed by Timmy's Handicar, Musk teams up with Nathan and Mimsy in an effort to reduce Handicar's positive publicity. This effort eventually escalates to a revival of Wacky Races, with Musk and his Tesla D competing against Timmy's Handicar and a variety of other cars. When Musk eventually takes the lead in the race, his car is attacked and overrun by other Handicars, and Timmy's Handicar wins the race. Because of this, Elon Musk decides to buy the rights to Handicar from Timmy for $2.3 billion, a deal that Timmy accepts. (Source: Fandom.com, CC BY-SA)
