Have you ever intimidated someone with your intelligence?

How did you find out? Did you do it on purpose or was it just how they responded to you? Why do you think they were intimidated by your intelligence (as opposed to, say, your fists).

I tend to think of muscles and brawn and guns as things to be intimidated by. Intelligence? I suppose if you were deliberately trying to claim you knew better, that could be intimidating, but I’m thinking of circumstances where the last thing you want is to be intimidating and yet, people are still intimidated.
