Who can tell a XX joke?

A patient came to see a psychiatrist. Patient: I always thought I was a bird. Doctor: Oh, that's serious. When did it start? Patient: Because I am a bird ... (2) A doctor in a mental hospital asked the patient: What would you do if I cut off one of your ears? The patient replied, then I can't hear you. The doctor listened: mm-hmm, it's normal. The doctor asked again, what will happen to you if I cut off your other ear again? The patient replied, then I won't watch it. The doctor is getting nervous. How could he not see it? The patient replied: because the glasses will fall off. (3) Two mental patients escaped from the hospital. They ran and climbed a tree. One of them jumped from the tree and rolled and rolled. Then he looked up and said to the man above, hey, why don't you come down? The person above answered him: No-OK-Ah-I'm not familiar with it yet ... (4) There is an old lady in a mental hospital who squats at the gate of the mental hospital wearing black clothes and holding a black umbrella every day. The doctor thought: to cure her, we must start from understanding her. So the doctor also wore black clothes, took a black umbrella and squatted there with her. They were silent for a month, and the old lady finally said to the doctor, are you a mushroom, too?
