Apparently, I look like three total strangers.
On three separate occasions, in three different states, I've had people approach me thinking I'm somebody else. In a bar in St. Paul ten years ago, one guy even talked to me for 10 minutes, thinking I was his buddy (I played along, 'cause I was bored). He asked when I got back into town, why didn't I call him, let's get together and jam this weekend, etc. My wife was in the bar; when she walked up to me, the guy looked at me like "what the hell - you're with her?" as if I had another wife/girlfriend/partner somewhere else. He looked confused, but he never did catch on; I finally just left the bar.
