When I was in college, we had the subject "Data Base". He had to write a course. As the teacher told us, he was very tired of coursework on standard topics, such as the database of the hotel, warehouse, clinic, taxi station, etc. He promised that the one who surprises him with an unusual theme will receive an additional point.
All the students put their brains on and started to work. There were databases of the veterinary clinic, MMO games, social networks. But most of all was surprised by one fellow student who brought the database of the Holy Inquisition.
He gives it, and they have this dialogue with the teacher:
“Yes, young man, you have no options in the column “Resultat of the Investigation” except “Fire a Witch on Fire.” This is a mistake, go correct it.
The student responds calmly:
How did you think it was a mistake?
