Gordian Knot

Phineas: There's a legend I've heard, or so it's been taught,
Baljeet: 'Bout Alexander the Great
Buford: And the Gordian Knot.
Phineas: Looked it up on the Net so that we could recreate it,
Now the knot we have here is quite complicated.
Isabella: It's got closed bends, loop splices, bowlines and lashings.
Phineas: Maybe we can loosen it with just a little thrashing.
Kids: Square knots, sheepshanks and all kinds of hitches.
Phineas: When it comes to constraint, there's an embarrassment of riches.
Kids: It's already a knot, so ready or not
We're gonna try to untie it, though it's terribly taut;
So it won't be for naught, we'll give it all that we've got
To untie the un-untieable knot.

Candace: We don't know what it is, but we know what it's not:
It's not a Gutenberg press or a coffee pot.
It's not a car or a tractor 'cause the safe's too small
And a fish or a piano wouldn't make sense at all.
Kids: It's already a knot, so ready or not
We're gonna try to untie it, though it's terribly taut;
So it won't be for naught, we'll give it all that we've got
To untie the un-untieable knot.
To untie the un-untieable knot.
To untie the un-untieable...

Candace: NOT!... even close.
