Didn't he used to live in Seattle?
I do get that feeling every once in awhile. I frequent some poultry forums and I have a unique user name (flyingmonkeypoop), everyone loves the name and I always post. I was at a show this past spring when I heard "Look! It's Mike the flyingmonkeypoop!" then I was surrounded by a few people all getting their pics taken with me and a couple folks offering to pay for my lunch, it was pretty awesome.
Then, I had a few moments locally. I have a page on facebook that I made as part of an inside joke. It all started off when one of my old coworkers asked why I did something, I told them because "I do what I want!" which started it all. Now I have the Mike Friggin Baker page on facebook and a handful of tshirts out there with my pic and "I'm Mike friggin Baker" on the front and "...and I do what I want!" on the back. Anyway, in the Inlander which is a local paper that has the I saw you/You saw me section, there was someone that posted that they saw a guy wearing a Mike friggin Baker shirt that was clearly not me and they wanted to hang out. After that, I had tons of people 'like' my page and folks come into my store and request pics with me for no reason at all.
