I haven’t heard anything I can repeat without getting death threats, so how about a joke mathematicians might appreciate? I’m sure the title of the each ‘proof’ resonates among us who try to get information from those more informed than us:
- Proof by deferral: “We’ll prove it next week.”
- Proof by cyclic deferral: “As we’ve proved last week…”
- Proof by indefinite deferral: ” As I said last week, we’ll prove this next week.”
- Proof by lack of imagination: “I can’t think of any reason why it’s false, so it must be true.”

Behold, they’ll take over your mind when you go out to the corner shop for lunch…… and make you empty your paypal account.
