Found this highly amusing mathematical proof that concluded that 1 = 2, so without further ado, here it is.
1. Let A = B
2. Multiply both sides by A.
A^2 = AB
3. Add (A^2  2AB) to both sides
A^2 + A^2  2AB = AB + A^2  2AB
4. Factor the left side of the equation, and collect right terms on the right
2(A^2  AB) = A^2  AB
5. Divide both sides by (A^2  AB)
2 = 1

i've seen it before.
xisnotx, get it?
it's the exact same proof.
you can define x as anything, even what it can't possibly be.
therefore, logic is limiting.

There are several variations on a theme of this proof. The error with all of them is division by zero (because A = B, the expression you factor out is zero, and 0*X = 0*Y is true for all values X and Y).
An argument is two people sharing their ignorance.
A discussion is two people sharing their understanding, even when they disagree.
