I thought I saw James Harden walking into my office building a few months ago. Same massive beard, pretty tall (but at the time... thought to myself "damn, I thought he'd be taller"). It looked
exactly like him, and a well-known protein/energy bar company is on my floor, so figured he may be doing some promo work with them (I think they work with other athletes). Not to mention, the Rockets were in town the night before and the dude is from SoCal, so was all but convinced it was him.
Fast forward about a month or so later, and I saw "James Harden" walking back to our building with a salad from the deli across the street and noticed his employee badge.
