The error is not in the definition of the Joke class, but somewhere it's being used. In most cases with errors like this, it's the result of a memory management error — some object (presumably a string) gets deallocated and another gets allocated in its old memory location. Try running with NSZombieEnabled and see if it turns up a message to a dealloced object.
