Of all the women I've dated, only one father tried to do the whole intimidation thing. He wore a 1911 in a holster. I asked him if I could see it. So he hands it over, I field strip it, criticize his cleaning job, show him how to properly clean a 1911, the correct places to lube (and how much), and reassemble it. From the look on his face, significantly faster than he could.
I kinda felt bad afterwards, though. He looked rather disappointed. His wife on the other hand thought it was hysterical.
