He is an idiot (as if we don't know already). The word "drop" is bad terminology not because 3-D space is a "mindfuck"; it is because, to eject something from the Moon, you have to first accelerate it beyond the Moon's escape velocity -- hardly an action evoked by the word "drop".
The asteroid that killed the dinosaurs is estimated to be moving at 40 times the speed of sound, which is less than 0.005% speed of light.
This is from the book Global Catastrophic Risks (an eye-opening book that I urge everyone to read), p225.

One would expect a "moonrock", unless accelerated by huge amount of energy, to be much less speedy.
That asteroid was also the size of Mt. Everest. I should have clarified a normal-sized projectile must travel at relativistic speeds.
