Appeal To Emotion:
See, my mom, she had to work three jobs on account of my dad leaving and refusing to support us, and me with my elephantitis and all, all our money went to doctor's bills so I never was able to get proper schooling. So really, if you look deep down inside yourself, you'll see that my fallacy here is the best.

Appeal to Fear:
If you don't accept Appeal to Fear as the greatest fallacy, then THE TERRORISTS WILL HAVE WON. Do you want that on your conscience, that THE TERRORISTS WILL HAVE WON because you were a pansy who didn't really think that Appeal to Fear was worth voting for, and you wanted to vote for something else? Of course not, and neither would the people you let die because THE TERRORISTS WILL HAVE WON.

If you don't agree that Appeal to Force is the greatest logical fallacy, I will kick your XXX.

Begging The Question:
Circular reasoning is the best fallacy and is capable of proving anything.
Since it can prove anything, it can obviously prove the above statement.
Since it can prove the first statement, it must be true.

Burden Of Proof:
Can you prove that Burden of Proof isn't the best logical fallacy?

Complex Question:
Have you stopped beating your wife and saying Complex Question isn't the best fallacy?

False Dilemma:
I've found that either you think False Dilemma is the best fallacy, or you're a terrorist.

False Premise:
All of the other fallacies are decent, but clearly not the best as they didn't come from my incredibly large and sexy brain.

Gambler's Fallacy:
In all the previous talks about this subject, Gambler's Fallacy won, so I just know the Gambler's Fallacy is going to win this time!

Guilt By Association:
You know who else preferred those other logical fallacies?

Since I've started presuming that correlation equals causation, violent crime has gone down 54%.

Red Herring:
They say that to prove your fallacy is the best requires extraordinary evidence, because it's an extraordinary claim. Well, I'd like to note that "Extraordinary claims demand extraordinary evidence" is itself an extraordinary claim.
