Excerpted from "The Children's Hour" by Henry Wadsworth Longfellow

A sudden rush from the stairway,
A sudden raid from the hall!
By three doors left unguarded
They enter my castle wall!

They climb up into my turret
O'er the arms and back of my chair;
If I try to escape, they surround me;
They seem to be everywhere.

They almost devour me with kisses,
Their arms about me entwine,
Till I think of the Bishop of Bingen
In his Mouse-Tower on the Rhine!

Do you think, o blue-eyed banditti,
Because you have scaled the wall,
Such an old mustache as I am
Is not a match for you all!

I have you fast in my fortress,
And will not let you depart,
But put you down into the dungeon
In the round-tower of my heart.

And there will I keep you forever,
Yes, forever and a day,
Till the walls shall crumble to ruin,
And moulder in dust away!
