GOT LYSOL?

One of my coworkers was at my desk talking when I noticed he had a booger. I was trying to decide if/how to tell him. I don't know if he felt it or noticed me looking at him strangely, but he wiped his nose. All of a sudden, it was like time was going in slow motion. After he wiped, a HUGE booger fell from his nose and it was headed toward my desk! I was hoping I was mistaken about the trajectory and it would fall on the floor but no such luck. I swear it actually bounced before coming to a rest near the edge. I tried to hide my luck of disgust. How do you politely tell someone to get their booger off your desk? At just that moment, another guy came into my cube. I turned my head to answer his question and thankfully, my coworker semi-surreptitiously removed the booger. I flooded the area with desk cleaner and an antibacterial hand sanitizer chaser but I'm still grossed out though. I lost my appetite so I'll have to save my mini Reese's Cups for later. What a way to start the morning...
