A man went to the doctor complaining of insomnia.

The doctor gave him a thorough examination and found absolutely nothing physicaly wrong with him, then sent him to his colegue psychiatrist.

The psychiatrist looked at the man and said to him, "Listen, if you ever expect to cure your insomnia, you have to stop taking your troubles to bed with you."

"I know," said the man, "but my wife refuses to sleep alone."

A woman went to a psychiatrist and said to him,

"I want to ask you about my husband. He thinks he's a refrigerator."

"Well that's nothing to worry about," said the psychiatrist. "I would say that's quite a harmless obsession."

"Yes, but the thing is," said the woman, "he sleeps with his mouth open and the little light keeps me awake at night."
