That Josh Groban Guy...

There's a guy who goes to school here who looks just like Josh Groban. I see him all the time and he intrigues me, naturally. I wonder if anyone has told him he looks like Josh. My friend and I were walking into the library today and he walked past. I always feel like I stare at him when I see him, but he never looks back so I'm safe. Anyway, my friend said "Wow, that guy looks like Josh Groban!" I explained to her that I often see him and think the exact same thing. I really want to say something the next time I see him, but don't want to come off as a creeper/stalker.
