walled city

sir! enemy forces are massed outside the walls!
have the archers ready.
sir! I don't think that will be enough. sir.
why not, centurion?
well, you see sir. our walls are little stones.
what do you mean? they look pretty big to me.
yes sir, but the enemy is. . . well it's huge sir!
how huge?
like they blot out the sun, sir!
ok. well that is pretty big, isn't it. what does the enemy look like?
like children sir! impossibly monstrous children. in bathing suits.
interesting disguise. commence firing.
sir! yes sir!
