The story went something like this:

Seargeant: When you are scared, what do you do?

Recruit: Keep on fightin’

Seargeant: Good for you. And now they shoot off your right ear…what then?

Recruit: Keep on fightin’!

Seargeant: Excellent. But now they also shoot off your left ear, what then?

Recruit: Then I can’t see.

Seargeant: Can’t see? What school did you come from?

Recruit: Well seargeant, when both my ears are gone my helmet falls down…over my eyes.
