My sister is notoriously blonde.
I had just taken Microbiology where our professor was trying to explain to us just how prolific bacteria were in our world. He told the class also that bacteria are important in our world, and that there are many beneficial bacteria we make us of ever day. For example, he asked the class who liked blue cheese dressing. A bunch of the class raised their hands. He explained that the mold that is used to culture the blue cheese is a very common mold. Often it is found in bathrooms that aren’t kept clean. He tells us, "So the next time you have blue cheese dressing, think of public restrooms."
Well, my sister loves blue cheese. Being a brother, I had to point this out to her. So I tell her, "Hey, did you know that the same mold that makes blue cheese grows on toilets in public restrooms?" and in all seriousness, she says emphatically, "Bullshit. Do you know how illegal it would be to go around scraping urinals to make blue cheese dressing?"
For one of the few moments in my life, I was speechless. Its now one of my favorite stories to embarrass her with.
