Mike Rowe doesn't recognize James Hetfield, then calls him Lars Ulrich
Large Tattooed Man: Sorry to interrupt, you're Mike Rowe right?
Mike Rowe: I'm him.
Large Tattooed Man: I just wanted to tell you I enjoy your shows, and really appreciate what you're doing for the skilled trades.
Mike Rowe: Sorry. You guys local?
Large Tattooed Man: I live around here, and Sophia's from Argentina.
Mike Rowe: That's nice. What part?
Sophia: Buneos Aries.
Mike: I was there a few years ago. Beautiful place.
Sophia: It is.
Mike Rowe: So what do you do around here?
Large Tattooed Man: I play in a local band.
Mike Rowe: Cool! I love local bands. What kind of music?
Large Tattooed Man: Rock and Roll.
Mike Rowe: Nice. What do you call yourselves?
Large Tattooed Man:: Metallica.
Mike: Oh my God. Of course. You're Lars Ulrich. Forgive me. I heard you lived around here. What a pleasure to meet you.
Large Tattooed Man: Actually, my name is James. James Hetfield
Despite Rowe's screw-up, Hetfield was pleasant:
"For what it's worth, I know that Metallica consists of several people who aren't Lars Ulrich, but earlier this week, someone told me Lars lived in the neighborhood, so his was the name that shot into my head when I finally realized I was talking to the lead singer of Metallica. Point is, I knew you weren't Lars before I called you Lars, but I called you Lars anyway - which brings me back to the aforementioned idiocy, and my own slow unraveling. Regardless, if we meet again, I'll get it straight. Promise.
"In the meantime, this will likely endure as my favorite botched encounter for a very long time."
