Luis Zwiebach and his team received an emergency call to check out a stuck elevator. Was there a ghost in the machine? If Rene Descartes were an elevator technician, he might have said yes. British philosopher Gilbert Ryle would have chided him, “No way, Descartes; maybe it’s your famous evil demon!”

Zwiebach and his team discovered, in this case, it was in fact an evil demon — an evil minion to be precise.

At least he looks friendly.
