Elon Musk's Father's Day was all sci-fi and tech, of course

Like many dads around the world, Elon Musk is spending his Father's Day making bad dad jokes and receiving the gift wrapped fruits of being a good parent.

First, Musk took to Twitter to let his kids (who must be sci-fi fans, too) know that he's not just a space and electric car mogul, he's also on the dark side of the Force.

Later, Musk seemed a little giddy when he posted a photo of a gift he received for Father's Day: a luxurious, personalized iPhone case.

Based a quick look at the Chaos Club website, the gold chain adorned case may have cost as much as $350.

That's not the most expensive gift you can give a billionaire, but when it comes to the often janky gifts we give our understanding dads, this ranks pretty high on the swag scale.

Yes, even Mars-loving space geeks who plan to bore holes into the earth to move around Los Angeles faster get a little warm and fuzzy on Father's Day.
