This post is as good as itself

A post on the Guardian sports blog contains two new types of tautology.

In work on tautologies, in philosophy/semantics/pragmatics, it's normal to give examples like 'War is war', 'Boys will be boys', 'If it rains, it rains', and 'Either he'll come or he won't'. It's also normal to point out that tautologies can have these forms:

Equative: e is e; an e is an e
Conditional: If P then P
Disjunctive: Either P or not P

It's not so easy to think of tautologies that have forms not on this short list (of course with a bit of propositional logic you can come up with as many tautological forms as you like, but what we're after here are sentences that someone might actually produce).

The new examples are after the jump.
