Did the Mars rover operators draw a penis on the surface of Mars?
Patient: "I see sex everywhere."
The doctor shows him a blank white sheet: "What do you see here?"
"It's a white sheet, and people are having sex on it."
The doctor shows him a black sheet: "And what do you see here?"
"It's a dark room with a bed, and people are having sex on it."
Doctor: "Okay, patient, wait in the hallway, I'll think about how I can help you."
The patient goes out and says at the door: "Doctor, aren't you ashamed to show such pictures?"
These guys seem to have the same problem.
