Mnemonic for Fallacies of Relevance
In an episode of Family Matters called Emotional Irrelevance, Carl Winslow uses a Baculum to smash Steve Urkel’s Misericordiam that Steve used to appeal to the populum. Shifting the focus to other things that happened, Steve used an Ad Hominem against Carl in retaliation but it was a red herring. The audience ignored the ratio enlenchi and missed the point completely. Behind the scenes, the straw man had an accident with oversimplifying and then misapplying a general rule to a specific case.
Mnemonic for Fallacies of Sufficiency
A hasty general-ization called conclusion, started drawing a slippery slope without a picture of it and predicted it would turn out bad. His wife pointed to the picture he had painted on their honeymoon of her butt and indicated it was exceptional and that she was sure the current drawing would be just as good, but he thought this a weak anal-ogy.
