You may not know this, but I went to high school with professional golfer J.P. Hayes -- he and my brother were classmates. But that doesn't make me a professional golfer -- in fact, I couldn't break 100 if I had the only pencil on the course.
Why bring that up? Because some people seem to think that because Rush Limbaugh and the moron Florida pastor who wants to burn Korans both went to the same high school, it has some significance.
The only conclusion I can draw? There are a lot of people who have gotten through high school without learning the post hoc, ergo propter hoc fallacy.
How does it work? This is the example I learned when I was young:
On a cold day, a cat put its kittens in the oven
Biscuits are always put in the oven
Kittens are biscuits
So what can we conclude about the relationship between these two high school classmates? Nothing. But go ahead and have a biscuit if you think otherwise.
