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
