Shares in Tesla took a nosedive in after-hours trading today as Elon Musk cut off analysts during a first-quarter earnings call. He dismissed a question about gross margins from Bernstein senior analyst Toni Sacconaghi as "boring." Instead, Musk and other executives answered multiple questions from a Tesla enthusiast and Youtuber named Gali Russell.

The 25-year-old retail investor tweeted at Elon Musk on Monday, seeking to ask him a "crowdsourced" question during Wednesday's conference call. Instead of a single question, Russell was able to ask several.
