From "Monty Python and the Holy Grail"

NARRATOR: The Tale of Sir Launcelot.
FATHER: One day, lad, all this will be yours!
HERBERT: What, the curtains?
FATHER: No, not the curtains, lad. All that you can see! Stretched out over
the hills and valleys of this land! This'll be your kingdom, lad!
HERBERT: But, Mother--
FATHER: Father, I'm Father.
HERBERT: But Father, I don't want any of that.
FATHER: Listen, lad. I've built this kingdom up from nothing. When I started
here, all there was was swamp. The king said I was daft to build a
castle in a swamp, but I built it all the same, just to show 'em. It
sank into the swamp. So, I built a second one. That sank into the
swamp. So I built a third one. That burned down, fell over, then sank
into the swamp. But the fourth one stayed up. An' that's what your
gonna get, lad -- the strongest castle in these islands.
