A mole of moles

Only someone as twisted and intelligent and educated as Randal Munroe would be able to answer the question, "What would happen if you were to gather a mole (unit of measurement) of moles (the small furry critter) in one place?" and to then take the answer to a place where we get a sentence like this, "Plumes of hot meat and bubbles of trapped gases like methane—along with the air from the lungs of the deceased moles—periodically rise through the mole crust and erupt volcanically from the surface, a geyser of death blasting mole bodies free of the planet."

I love Randal Munroe.
