There isn't a really good back story to this quote. I got called upstairs this afternoon to be asked a question by my mother. That question was, "What disease did Typhoid Mary spread?"
I had to just look at her with an disbelieving face. Really? Did you just ask me what disease TYPHOID Mary spread. At long last I said Typhoid Fever. As soon as I gave my answer mom couldn't stop laughing over her inability to think about what the name "Typhoid Mary" meant.
So that is my Quote of the Day
Oh, and for those of you who don't know who Typhoid Mary is, I suggest you go look it up on Wikipedia. Because Wiki is amazing. :)
