When I was in college I worked for a mycologist (a guy that studies fungi). He had been fairly famous back in the 50's because he had developed a couple of very important antibiotics including Streptomycin. One day I found a really pretty orange mold in my coffee filter. Go figure! I took it to the Prof to get him to identify it for me. He threw me out of his lab and told me to never bring it back it back. Apparently someone had done the same thing and the spores had spread throughout the lab and contaminated everything.

OK, so it was just a little off topic.
