Favorite theorem

Hey /sci/, what's your favorite theorem in math?

I think mine has to be Stokes's Theorem stated in terms of differential forms. (Vector form = EPIC FAIL)

While I agree that Stokes' theorem is great (except the bullshit version that the physics students learn, del cross dot bullshit), I'm awfully fond of the Gauss-Bonnet theorem.

My favorite theorem is the one which will be developed in the future, establishing RH in the affirmative.

Ramanujan joint work with Hardy on assymptotic of partition function

What if it's a computer-assisted proof, similar to the one that proved the Four-Color theorem? I.e., what's better--killing a lion by chasing it down and hunting it with a spear, or just nuking all the niggers in Africa and picking up the pieces that are left over? I'd be terribly disappointed if any of the Millenium Problems were solved by computer-assisted proof too complex to be checked by hand.

On a similar note, one proof that will be absolutely bitchin' if it's ever finished is the Atlas.

What is the Atlas conjecture?
