Second one - I had to do safety training on Blood Borne Pathogens to the whole plant. My first year I was trying to say that a Bloodborne is a micro-organism and I said it was a mico-orgasm. One employee piped up with "I didn't know you still had those at your age". For the next ten years I had to stop before I used the term. It was never forgotten and employees would wait for me to slip up again.
