Missing off the top of my head:

• proof by duration: it’s been working for so long, why change it now?
• proof by populism: it’s served so many people well
• proof by gaslighting: technically speaking Trump won 3 presidential elections in a row
• proof by marriage: I’m married to Usha Vance and we have kids, how could I possibly be gay?
• proof by omission: there’s no proof he’s a criminal, he never release his tax records
• proof by silence:
• proof by flooding the zone: nobody is talking about that anymore

Proof is left as an exercise for the reader: I forgot the proof in undergrad and so will you

"The proof is left as an exercise for the reader" is my fave

I've found the equation that can calculate anything in the universe. A = f(x), where f(x) is the equation for the specific thing you want to calculate, you just have to put it in.

Lack of space was Fermat's excuse for not proving his last theorem.

Physics also has the proof by "experiment says so, therefore we just add in some constant to make the equation work"

It was revealed to me in a dream

Proof by break: Before the break: "We will proof this theorem after a short break", After the break: "As we have proven before the break…"
Proof by unavailable literature: The prrof can be found in a publication only available by in-person request in one library of one university in Brno, Czechia. That closed 30 years ago.

important repository of similar content here. Thank you University of Utah.

I like the credo quia absurdum

A proof is a proof. What kind of proof? Its a proof. A proof is a proof, and when you have a good proof, its because its proven.

The second and third are at least related

Don't forget the proof by aliens...

Proof by proof: the bread rose therefore…

Hey, does anyone know if this visual style is some kind of PowerPoint template? I've seen slides with a similar aesthetic before.
