Rorschach Test

(not my joke but worth repeating) A psychologist was treating a man and administered the Rorschach Test to him. In this projection test, the patient tells what he sees in random ink blots like angels, devils, monsters, etc. After the test, the shrink says, “I should not tell you this, but you have the dirtiest, filthiest, most disgusting mind of anyone I ever treated.”

The patient replied, “You are criticizing me? You are the one with the dirty picture collection!”
