Over two decades ago at Gay Pride in Boston when I was single, I was dancing with a friend when I found myself face to face with a well-built guy that looked familiar, but I couldn't immediately place him. He ran his hand across my pec, which was stubbly from being recently shaved, and smiled, but I was not into returning the affection and/or hooking up because at the time I was kind of dating someone I was smitten with (who was not, as it turned out, smitten with me). And it hit me who he reminded me of. So I said to him, "Has anyone ever told you that you look a lot like that porn star, Phil Bradley?" And he had a completely blank look on his face (and moved away soon after). But I knew it could not be him, because the guy in front of me was really short, like 5'5", and from what I could tell, Phil Bradley looked like he was 5'10" or more, and seemed to be a big guy.
I told that story a year later at a party, and one of the guys there started laughing and said, "That was definitely him. And he IS short. And he's got that completely blank look on the face act down pat."
