Jokes: Methods of proof

How to prove it

(from http://www.workjoke.com/mathematicians-jokes.html )

proof by example:
The author gives only the case n = 2 and suggests that it contains most of the ideas of the general proof.
proof by intimidation:
“Trivial.”
proof by vigorous handwaving:
Works well in a classroom or seminar setting.
proof by cumbersome notation:
Best done with access to at least four alphabets and special symbols.
proof by exhaustion:
An issue or two of a journal devoted to your proof is useful.
proof by omission:
“The reader may easily supply the details”
“The other 253 cases are analogous”
“…”
proof by obfuscation:
A long plotless sequence of true and/or meaningless syntactically related statements.
proof by wishful citation:
The author cites the negation, converse, or generalization of a theorem from the literature to support his claims.
proof by funding:
How could three different government agencies be wrong?
proof by eminent authority:
“I saw Karp in the elevator and he said it was probably NP-complete.”
proof by personal communication:
“Eight-dimensional colored cycle stripping is NP-complete [Karp, personal communication].”
proof by reduction to the wrong problem:
“To see that infinite-dimensional colored cycle stripping is decidable, we reduce it to the halting problem.”
proof by reference to inaccessible literature:
The author cites a simple corollary of a theorem to be found in a privately circulated memoir of the Slovenian Philological Society, 1883.
proof by importance:
A large body of useful consequences all follow from the proposition in question.
proof by accumulated evidence:
Long and diligent search has not revealed a counterexample.
