Inspired by netikras leg hair story reminded me of another hair story.

I was training to maintain a Bailey DCS system about 15 years ago. So I was working with the consoles and learning the software. My mentor at the time was talking to me about this. He was a heavy set fellow with a Phd in control theory. His eyes kind of naturally stuck out of his face a bit. I assume blood pressure of some sort.

mentor: "Hey, I can see you have working on the consoles on the system."

me: "How is that?"

mentor: "I found a curly hair." (I have curly hair when it gets longer.)

me: <me, saying this very slowly and deliberately> "How...curly...was...it?"

At this point he started laughing by rapidly blowing air out of his nose, his eyes bulged out further, he kept his mouth mostly closed. He was trying to be professional and not laugh at such base joke.

me: "I mean if its really curly it could be anyone."

Then he lost it and started laughing out loud. We never spoke about it ever again.
