Coincidentally I received this joke in an email today:

The Bathtub

During a visit to a private mental health facility a visitor asked the Director what the criterion was which defined whether or not a patient should be institutionalized.

"Well," said the Director, "we fill up a big old fashioned 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," said the visitor. "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."

(PS…..Your room will be ready shortly……)
