The Professor's Guillotine was a roughly five-foot tall miniature guillotine the Professor created in order to help Ginger and Mary Ann to split coconuts. Resembling the guillotines of the French Empire, the ghoulish device terrified Gilligan, the Skipper and the Howells with the Professor completely oblivious to their discomfort and to his excited glee with how well it performed. By time Mary Ann and Ginger showed up with the newspaper account of the murder of Randolph Blake, he finally understood everyone's skittishness to him and the device as well as its enormous potential to fatally injury someone. It is very likely he disassembled it afterward.
