I have argued with PHD's who used the same tactics as anax describes.. once you get em flustered. Other than that.. I have found that I GENERALLY have a better debate with educated people.
There are plenty of academics who act like little children.
The fact is we all use fallacies from time to time because they're fun, especially when your opponent doesn't know what hit them. My favorite is this:
9/11 Conspiracy Theorist: The Republicans are behind 9/11.
Me: But Noam Chomsky doesn't believe the Republicans would do that, and he believes in all sorts of conspiracy theories. If Noam Chomsky doesn't believe it, it can't be true.
9/11 Conspiracy Theorist: I thought Chomsky was smarter than that.
