The bathtub test
During a visit to a mental asylum, a visitor asked the doctor, “how do you determine whether or not a patient should be institutionalized?”
“Well” said the doctor, “we fill 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 see” said the visitor, “A normal person would use the bucket as it is bigger than the teacup or teaspoon”
“NO” said the doctor “A normal person would pull the plug.”
“Do you want a bed by the window?”
