You can actually overdo it by identifying things that look like fallacies but really aren't fallacies.
Let's take the appeal to pity, for example, and take those shows that they have on late night television of starving kids who need a sponsor through the Christian Children's Fund. Because it is never pretended that this children merit assistance, but only that the need assistance, there is no appeal to pity. In order to appeal to pity to be a fallacy, there has to be a question of merit that is initially presented, and then resolved by an appeal to pity.
One of my favorite things in the movie About Schmidt was Jack Nicholson's letters to his sponsored child, Ndugu.
