Bernstein analyst Toni Sacconaghi was one of the analysts Elon Musk cut off on a Tesla earnings call Wednesday night.

Musk interrupted a question Sacconaghi was asking, calling it a "boring bonehead question," then the CEO interrupted another analyst in much the same way and turned the conversation over to shareholder Gali Russell, who asked several questions via YouTube.
