I recall two recent cases:

* An attempt to change the master code of a secondhand safe. To get useful information I had to repeatedly convince the model that I own the thing and can open it.

* Researching mosquito poisons derived from bacteria named Bacillus thuringiensis israelensis. The model repeatedly started answering and refused to continue after printing the word "israelensis".

> israelensis

Does it also take issue with the town of Scunthorpe?
