Oldie but goody:
A guy goes to see a psychoanalyst who shows him an ink blot, and says "What do you see?".
Patient replies: "A man and a woman making love."
The psychoanalyst shows him another ink blot - "OK, so what do you see this time?"
"Another man and woman making love" says the guy.
Psychoanalyst says: "You're completely obsessed with sex."
"What do you mean I am obsessed'? You are the one with all the dirty pictures".
