I guess the first thing I would have to do is buy an MP3 file of the Barenaked Ladies song. Then, with the remaining $999,999.01, I would shop for a new camper van, stereo system for that van, cabinetry and appliances to customize it, go crazy at the local game store and sporting goods store, and then spend whatever was left on gold or silver at a coin shop.
Edit: I hope the link works internationally!
Lol.
Perhaps there is an NFT version and it can be yours forever.
An off-grid home would be a decent way to spend it. A few rifles and ammo too.
I may or may not already have suitable firearms, but if I had a million dollars, there are definitely a few upgrades I would consider. A nice precision rifle and a pallet of match grade ammunition would be sweet. A proper over/under skeet and trap shotgun would also be nice. And as an American, it would be my duty to buy a nice AR10-pattern .308 rifle and kit it out properly.
