Yep, this guy below...
I was in Amoeba Records, Hollywood, up in the DVD departments, perusing through Region-2 DVD's, when all of the sudden, I glance up, and sure enough, the baby blues and bushy black brows are likewise browsing through an aisle in front of me, a scraggly hippy beard and a red cap abreast his noggin.
I don't know whether or not it was because people were respecting his privacy (being there with whom I take was his petite Asian girlfriend/significant other) or the fact that nobody knew who he was -- either choice is applicable -- but nobody bothered him, which was cool. I chose to do likewise. I tried to take a picture on my cell phone, but was trying to shy away from being obvious.
He left shortly after, but it was the coolest (and most random) celebrity sighting I've seen since Matthew Fox (far, far before Lost, circa Party of Five) habituated my local Best Buy years ago.
