Greenlight Capital president David Einhorn tweeted Friday he got the pairs of short shorts that fellow billionaire Elon Musk promised him last week.
Einhorn added a tongue-in-cheek comment that the shorts “did come with some manufacturing defects,” he said.
Musk did not confirm on Twitter that it was him who sent the shorts.
UPDATE: CNBC learned that apparel maker Chubbies were the ones who sent the shorts to Einhorn. The San Francisco-based online clothing brand offers a host of loudly-colored short designs, with most keeping to a very short 5.5-inch inseam.
Kyle Hency, one of the founders of Chubbies, told CNBC that Musk did not ask them to send the shorts, but they would continue to send them to his short-selling foes if the Tesla CEO wants.
Musk responded to the revelation that it was Chubbies with a laughing face emoji, saying, “awesome.”
The briefs battle royale began after Einhorn’s hedge fund said in a letter he was “happy that his Model S lease ended” and was replacing the car because of problems with the technology.
