I'm sure quite a few of us on this forum enjoy messing about with logical contradictions, fallacies, errors in expression, (EDIT: and paradoxes). That said, I was hoping to find out what people's favorite logical contradictions, expressed logical fallacies, errors in expression, (EDIT: and paradoxes) are. Here are two of my favorites.

Cutting people is a crime. Surgeons cut people. Therefore, surgeons are criminals.

Cutting people in the context of an assault is a crime. Surgeons cut people with consent or at least with life-saving intent. Therefore, no.
He knows. It is a logical fallacy called "equivocation." The point of this thread is to list said fallacies, etc.
0 = 0 + 0 + 0 + 0 + ...
0 = (1 + -1) + (1 + -1) + ...
0 = 1 + (-1 + 1) + (-1 + 1) + ...
0 = 1 + 0 + 0 + 0 + ...
0 = 1
0 = (1 + -1) + (1 + -1) + ...
0 = 1 + (-1 + 1) + (-1 + 1) + ...
0 = 1 + 0 + 0 + 0 + ...
0 = 1

Everything I say is a lie.
True(ish) but makes you scratch your head:
02 = 0
01 = 0
00 = 1

This makes my eyes bleed!
Just to join in: 1+1=2. (contradicting my statement in the last thread)

a=b
a^2=ab
a^2+a^2= a^2 + ab
2a^2 = a^2 + ab
2a^2 - 2ab = a^2 +ab - 2ab
2a^2 - 2ab = a^2 - ab
2(a^2-ab) = 1(a^2-ab)
2 = 1
prove me wrong
a^2=ab
a^2+a^2= a^2 + ab
2a^2 = a^2 + ab
2a^2 - 2ab = a^2 +ab - 2ab
2a^2 - 2ab = a^2 - ab
2(a^2-ab) = 1(a^2-ab)
2 = 1

Seraph: your division of both sides by (a^2-ab) is invalid, as that's dividing by zero, because since, as stated above, a^2 = ab, a^2-ab = 0.
So the second-to-last line becomes:
2(0) = 1(0)
And division by 0 is fallacious.

And division by 0 is fallacious.
An even easier way of using Seraphimsan's trick:
x=2x
Divide both sides by x:
1=2

x=2x
Divide both sides by x:
1=2

Damn. You found my source!
Slick link!
I'd seen firedraco's before, but not Seraphimsan's... There's stuff in there I never would have thought of doing...
