Don't forget the customary "Utils" class which always contains lots of hidden gems like reimplementing 75% of the string manipulation functions provided by the standard library - some being unique implementations, others being a single call to the underlying standard library :)
I've been lucky enough to work on several occasions with code that wasn't like this and it was a joy to maintain. Cherry on the cake, that type of code usually comes with some automated tests.
