A teacher asked the class to bring in something medical for the next domestic science class.
Little Mary brings in a roll of bandage and some Germoline
"Very good Mary" says the teacher.
Tommy brings in some Iodine and a roll of cotton wool.
"Excellent Tommy".
Twenty minutes late, the tearaway of the class comes in trundling an iron lung - the teacher is flabbergasted.
"Where on arth did you get that Johnny"
"It's me dad's"
"Didn't he say anything when you took it?"
"yeah - aaaghhhhhhhh!"
