They did it last season too just as pizzagate started. Elon Musk was shown to be a fraud when he opens the door via "voice command" which doesn't work. Then instead of getting everyone to mars all he has is a "pizza pocket" that can feed 30 people, Cartman's like "okay", the joke makes no sense really except it was a week or 2 after pizzagate started. And then Musk goes off falling in love with Carman's girlfriend because she's so smart and funny. Musk even tweeted after the episode https://twitter.com/elonmusk?ref_src=twsrc%5Etfw&ref_url=http%3A%2F%2Fwww.siliconbeat.com%2F2016%2F11%2F23%2Felon-musk-uses-south-park-fire-back-trolls%2F
