Colin the Cleaner

A game for the Sinclair Spectrum, a computer almost as powerful as a Cray, but not quite, and undoubtedly the best in the world, but not this world, had as its name, a name remarkably similar to that of the one who takes care (Colin the Cleaner), was based on a cleaner, called Colin, who was required to remove the rubbish from 15 rooms of a museum, without dying, as often happens in museums. The player's job was to guide Colin round the museum.

The school caretaker's job is to take care not of a museum, but a school.

Fortunately, there is no player to guide him round, because it would be silly to guide a live person round the school (especially one who died when he walked down steps).
