"If he should say 'How came you here?'
(The way that you began, Sir,)
In such a case your course is clear—
'On the bat's back, my little dear!'
Is the appropriate answer.

"If after this he says no more,
You'd best perhaps curtail your
Exertions—go and shake the door,
And then, if he begins to snore,
You'll know the thing's a failure.
