According to the Obj-C docs [1], you can invoke NSObject instance methods on a class object:
"So that NSObject's methods don’t have to be implemented twice—once to provide a runtime interface for instances and again to duplicate that interface for class objects—class objects are given special dispensation to perform instance methods defined in the root class. When a class object receives a message that it can’t respond to with a class method, the runtime system determines whether there’s a root instance method that can respond. The only instance methods that a class object can perform are those defined in the root class, and only if there’s no class method that can do the job."
I thought I read this long ago in the NSObject API docs, but can't find it now. Anyway, at least this doesn't work just by accident (I checked because I use this trick myself :).
