Proof

In the immortal words of Jean Chrétien, "A proof is a proof. What kind of a proof? It's a proof. A proof is a proof, and when you have a good proof, it's because it's proven."

The Word of Our Jean.

Opposition leaders demand proof budget changes won’t cost N.S. money

HALIFAX — Nova Scotia’s opposition leaders are demanding written assurances that the province won’t lose any money because of unilateral changes the federal government made to the equalization formula.

...

Liberal Leader Stephen McNeil said the premier is stretching credibility when he talks about a deal without documentation to back it up.

Imagine that! A legislative opposition which, rather than meekly and mildly taking the government and Premier at its word on something, demands proof.

The novelty! The utility! McNeil should rush, rush, rush to the patent office on Monday; subject to the rules of prior art, he might just have something here, something he could sell to other provincial oppositions.
