Ed, Edd n Eddy: Psychology Manual
Psychology → Psychological Tests → Rorschach Test
Double D receives a psychology manual in the mail which describes the latest techniques in studying abnormal human behavior. He shows Ed and Eddy inkblots and asks them to interpret the blots. It is important to note that the Rorschach test is not a new technique; it was created in the 1920's and widely used in the 1960's.
