That was my first thought too. Uninviting the groom also works.

Oh, you can un-invite one of the in-laws for some amazing chaos too.

Uninvite the groom take his place.

You usually invite guests to the wedding, so I'd assume bride and groom would be safe under this logic.

The parents however....

And if two people uninvite each other, does that remove their uninvite-privilege, thus making the uninvite invalid and creating a paradox? Or would they have to fight for it over a lava pit or a chasm with either swords or massive cotton swabs?

How would removing both cause a paradox? Removing a guest doesn't remove their Plus One, so why should removing the guest remove their Minus One?

That's how you get the $NaN glitch in your bank account, but also for some reason Keanu Reeves is the officiant while holding akimbo pistols, and everyone's outfit includes a green sweater

so a kind of stack overflow?

Dear Mr. Holloway.

I will be attending your wedding. I choose you as my Minus One. Please do not show up.

What is this math you speak of?

Y es, un the sense that if you are invited, someone uninvites you, then you can plus one yourself.

But if you bring a plus one they can me minus one'd and you can't do anything to prevent it.

Based on the progression of BIDMAS/PEMDAS, addition always is first, followed by subtraction.

no questions asked

Yes.

Eloping was one of the best decisions my wife and I ever made. We still spent a bunch, but it was for the two week vacation that went along with the elopement instead of 3-4x that for a single day.

Just uninvite the bride.

you can uninvite one person of your choosing

According to the terms, yes. Shoulda said "guest."

Prevents objections

uncle Steve ends up attending because of a buffer overflow

I saw that Black Mirror episode... No, thank you.

No one said you can only uninvite guests

Oh, well, imagine...

I uninvited the bride. problem solved
