As some of you may know, I have used the quote "Combating ignorance one moron at a time" for quite a while now.
While still very appropriate, I have found a new quote that may come in handy... It's slightly more politically correct (which I'm sure you also know I'm always concerned with), but portrays the same feeling as the aforementioned quip...
So, without further ado: "There are no stupid questions, but there are A LOT of inquisitive idiots."
...says it all, no? :)
