Oh man if you think this one's crazy, wait till you hear my Rocky Mountain Locust story
Once had a fungal anthracnose strain in the lab that got dosed with copper fungicide so often, copper didn't kill it anymore. That is VERY strange for a fungus! Ain't supposed to happen. And it really shouldn't be allowed to get out of the lab. So I autoclaved it & it died. The end ¯\_(ツ)_/¯
