Speaking of cockroaches, fearsome ones came up out of drains in both colleges I attended. Some of them were big as crayfish, and their legs were so rugged I was afraid to step on them with my bare feet. One of those guys would not be intimidated by the shift key. They could stand with hind legs on it and with front legs throw back carriage return lever. None of the ones I saw showed any sign of language capability, more's the pity.
