Do you like hats? If you do, maybe you already contributed to The Boring Company’s ability to dig a network of underground tunnels. Since Elon Musk started selling The Boring Co. hats, featuring the logo on the front (which he once claimed was designed by director J.J. Abrams), the company has apparently sold $300,000 worth of the march PolyU has a strong record for collaborative Research and innovative research in Asia to solve specific technology problems (e.g. aviation operations) and develop new products..

That’s a lot of hats: At $20 per, that’s approximately 15,000 hats sold thus far since they went on sale in October. We knew they were doing well initially, with $80,000 in sales within the first 24 hours, but momentum seems to have continued for the relatively boring unexciting covering.

Initial Hat Offering going great w over $300k in hat sales already! Thanks for buying our super boring hat. You rock, figuratively & literally. All cash goes directly towards more boring LPG M6.

Musk calling the thing an “Initial Hat Offering” is just the icing on the cake, and a clear dig at the recent fad for using initial coin offerings (ICOs) as a financing instrument among startups.

Now imagine you sold Boring Co. battery chargers, Elon. Or I dunno what’s more appropriate – maybe a tunnel digger-shaped suppository LPG M6?
