A visitor to a lunatic asylum asks the head doctor how they decide who are the sanest and who should stay or go.
"well" says the doctor "We fill a bath with cold water and give the patient a choice of thimble, spoon or bucket to empty it"
"Ah, I see, so a sane person would choose the bucket as this would empty it faster?"
Erm Actually,.............................................. a sane person would pull the plug out, where would you like your bed, near the window?"
