Booger Flicking co-worker

One afternoon after lunch I was sitting in my cube and felt something stuffy up my nose.  I picked; it was a sizable, round, and mushy booger.  So out of my love for projectile physics, I sent it flying violently over the cubical wall, into the walkway.  That's where I thought it would land. Unfortunately due to the high density, aerodynamics, and skillful aim, the booger made it across the walkway into the shipping and handling guy's cube, who had been talking continuously on the phone.  I know it hit because two seconds after the launch, I heard him digress suddenly with an expressive:  "What the FUCK is this!" I know it is not nice when one gets hit with a booger, and I'm really sorry.  But at that time I couldn't stop laughing.  His natural reaction to such an unfathomable occurrence was absolutely priceless.
