The Poincaré Conjecture has Been Proved 307
Martin Dunwoody, a famous mathematician who works in the field of topology has a preprint that provides a proof of the Poincaré conjecture. This was one of the seven Clay Mathematics Institute millenium prize problems (reported on Slashdot here). The solution to each of the problems carries a monetary reward of 1 million dollars. However there are a number of conditions that still need to be met for the prize to be awarded in the case of the Poincaré conjecture.

Charles Dodgson, somewhere thru the looking glass, is at tea with the Mad Hatter discussing this very matter.

R^3 is kind of a magical place. R^2 might not have enough wiggling room, but R^4 might have too much. There exists a cross product in only R^3.

assume a, b, c such that: a + b = c
then 5a + 5b = 5c
and 4c = 4a + 4b
adding the two: 5a + 5b + 4c = 4a + 4b + 5c
shifting some terms around: 5a + 5b - 5c = 4a + 4b - 4c
simplifying: 5 (a + b - c) = 4 (a + b - c)
dividing by the common factor (a + b - c): 5 = 4

Maybe we should give these problems to the people at the next ACM International Programming Contest.

2) Cows have forelegs and two back legs, equalling six legs.
3) Six is an odd amount of legs for a cow.
4) By 1 and 3 cows have both an even number of legs and an odd number of legs.
5) The only number that is both odd and even is infinity.
Cows have an infinite number of legs. QED.

Be careful how you phrase that last sentence - your carefree use of the word "obvious" in reference to math calls to mind an old joke:
Two mathematicians were talking one day about some recent work they'd done. One described a proof to the other but quickly glossed over a complicated step. The second one said, "Wait a minute - you didn't prove your last assertion." The reply: "It's obvious."
So the second mathematician wordlessly took a piece of chalk, went to the nearby blackboard, and began to fill it with long statements full of obscure symbols. Nearly half an hour later, he stopped writing, turned around, and said, "You're right. It is obvious."

But the first one is more likely the correct one
Which, I see now, is the one that had been used. Sorry.
