My clumsy hamplanet boss does it again. I work in a lab with a couple of narrow corridors. My boss is >100lbs overweight and has very poor situational awareness. Today I heard a crash to my right. When I looked up I saw what had happened. He was going through the corridor in one direction, a petite coworker was going the other direction. He kept to one side to make space for her and he knocked the goddamn dry erase board off the wall. Dude is always in the fucking way.  A couple of days ago I took a document to him in his office. He was eating a parfait, complete with whipped cream and strawberries. I'm sure that was his only actual fruit for the day.
