On Monday, after Tesla stock hit a company record $420 per share, CEO Elon Musk made a joke at the rare intersection of things that dads and middle schoolers might find funny, by pointing out that "the stock is so high."
In addition to finding that common ground, the Twitter acknowledgment also poked fund at Musk's own "funding secured" tweet from August 2018 that temporarily lost him his spot as Tesla chairman, and also got him in hot water with the SEC. In that instance he jokingly stated that he was "considering taking Tesla private at $420. Funding secured." At the time it was the latest example of what his critics view as his impulsive Twitter usage, and it also got him fraud charges after the SEC read it as a misleading of investors. In addition to having to briefly remove himself as Tesla CEO, it eventually cost him a $20 million fine.
In recent, less pot humor-adjacent Tesla news, the company recently unveiled their Cybertruck, which Musk said has gotten 250,000+ preorders. Though it's worth noting that they only require a $100 refundable deposit.
