Odd or Even?
Can anyone prove that 1 is an even number? In any case you can think of.

Nope, not unless you define "even" to mean something completely different.

Somerville is doing even side of the street parking during snow emergencies this year, but not on streets where you can already only park on one side, so for this winter 1 counts an even number.
Chew on that Gmal, I totally nailed this one.

Naw.
You can totally keep the same definition of 'even'.
You merely have to use a new definition of 'prove'.

a = b
a^{2} = ab
a^{2}  b^{2} = ab  b^{2}
(a + b)(a  b) = b(a  b)
a + b = b
2b = b
2 = 1
Since 2 is even, and 2 = 1, then 1 must be even.
a^{2} = ab
a^{2}  b^{2} = ab  b^{2}
(a + b)(a  b) = b(a  b)
a + b = b
2b = b
2 = 1
Since 2 is even, and 2 = 1, then 1 must be even.

You can also use the BanachTarski theorem.

Re: Odd or Even?
You don't have to change the definition of "even," just use a different one. f(x) = 1 is an even function, so it makes sense to say "1 is even" in that respect.

Only if this particular instance of 1 is also deep and crisp.

Re: Odd or Even?
You can prove that 1 is even, if you work in an inconsistent system. (By definition, an inconsistent system is a system where every statement can be proven; equivalently, it is a system in which there exists statement A such that both "A" and "not A" can be proven; any statement can be proven from "A & not A".)
[edit:]
This is a deeper statement than it seems, because it is very difficult to prove that a particular system is consistent. In particular, a system which includes integers with the usual (Peano) axioms is strong enough to "describe itself" (i.e. you can use integers to represent mathematical formulae and relations between them, such as "formula X can be proven from suchandsuch axioms"); such a system cannot prove its own consistency, unless it is itself inconsistent.
