Elon Musk started triumphantly selling literal red satin Tesla short shorts to celebrate the firm's stock climbing, and it crashed Tesla's online store

• Tesla CEO Elon Musk announced on Sunday that the electric-car company was selling limited-edition red satin short shorts.
• Musk has used short shorts to taunt Tesla short-sellers in the past.
• Tesla's stock rose last week after the company reported second-quarter delivery figures that beat Wall Street's expectations.

Tesla CEO Elon Musk tweeted on Sunday that his electric-car firm was selling limited-edition branded red satin shorts.

The price is listed as $69.420 on Tesla's website. Musk is fond of referring to 420, which has associations with marijuana, and famously landed in trouble in 2018 for vowing to take Tesla private at $420 a share. On June 28, he tweeted, "69 days after 4/20 again haha."

The shorts have "S3XY" on the back, a reference to Tesla's Model S, Model 3, Model X, and Model Y vehicles.

The shorts' description on Tesla's website reads: "Celebrate summer with Tesla Short Shorts. Run like the wind or entertain like Liberace with our red satin and gold trim design. Relax poolside or lounge indoors year-round with our limited-edition Tesla Short Shorts, featuring our signature Tesla logo in front with "S3XY" across the back. Enjoy exceptional comfort from the closing bell."

Three minutes after Musk tweeted the link to the shorts, he tweeted, "Dang, we broke the website." Reports said that Tesla's online store was briefly inaccessible.

As of Monday morning, only XL shorts were still available. It appears Tesla will ship the shorts only within the US.

Musk has previously released incongruous limited-edition merchandise.

In 2018, Tesla brought out a line of surfboards, and Musk's Boring Company venture sold a giant blowtorch called the "Not a Flamethrower."

The Tesla billionaire also has a penchant for short shorts, which he has sometimes used to taunt short-sellers betting against Tesla's stock.

Musk has a well-documented disdain for short-sellers, tweeting in October 2018 that "what they do should be illegal." He also sent assorted shorts to the billionaire short-seller David Einhorn in August 2018.

Musk first tweeted about releasing red satin shorts on Thursday, after Tesla reported second-quarter delivery numbers that beat Wall Street's expectations, sending its stock up by 10%.
