The Bathtub Test

During a visit to a mental hospital, I asked the director how do you determine whether or not a patient should be institutionalized.  

"Well," said the director, "we fill up a bathtub, then we offer a 

teaspoon, a teacup and a bucket to the patient and ask him or her to empty the bathtub." 

"Oh, I understand," I said. "A normal person would use the bucket because it's bigger than the spoon or the teacup."

"No." said the director, "A normal person would pull the plug.. Do you want a bed near the window?"

DO YOU WANT THE BED NEXT TO MINE ?
