A doctor was once teaching a class of medical students at a famous hospital in
Edinburge.An injured
man was brought in,and the doctor turned to one of
his students and asked him,"What's wrong with this
man?"
"I don't
know,sir," the student answered."Shall I examine him and find out?"
"There's no need to examine him," said the doctor."You should know without
asking questions.He has
hurt his right knee.Didn't you notice the way he
walked?He hurt it by burning it in the fire.You see his
trousers leg is
burnt away at the knee.This is Monday morning.Yesterday was fine,but on
Saturday the
roads were wet and muddy.The man's trousers are muddy all over.
The man fell down on Saturday night."
The doctor then turned to the man
and said,"You had your pay on Saturday and went to a public house
and drank
too much.You got muddy and wet on the way home.Because you had drunk too much,
you fell
on the fire and burnt your knee.Is that right?
"Yes,
sir," said the man.
