Insanely Cool Mathematical Proofs, Part 1:

Proving that Connor Murphy is evil

I spend both a lot of time and money on Connor, thus:
Connor = time * money

Since time = money
Connor = money * money

Connor = money^2 (money squared)

Money is the root of all evil, so:

Money = √evil

Thus,

Money^2 = evil

Connor = money^2 = evil

Therefore,

Connor = evil

Boom. Math.
