Pick up a famous person (real or fictional) whom you might think have a personality disorder and analyze it based on the PPT provided.
Examine the extent to which their behaviour is consistent with the criteria/symptoms and/or determine if there would be a low/moderate/high likelihood of the individual being diagnosed by a clinician. You could also narrow in on some specific aspect of a personality disorder and examine that in isolation, which would obviously not be diagnosable in any regard.
