Script Perimeter and Circumference, a la Shmoop.
- 00:07
Welcome… to King Area’s court.
- 00:09
You’ve probably heard of his famous brother-in-law… the one with all the knights and whatnot.
- 00:16
Well, King Area doesn’t go in for all the swordplay and dragon-slaying.
- 00:20
He’s more interested in measuring stuff.

It’s so much less stressful. He has assigned a particularly important job
- 00:30
to two of his right-hand men…
- 00:32
Sir Cumference and Perry Meter. The King has asked that they get together
- 00:36
and decide on plans to build a tall stone wall around the castle.
- 00:39
Again, it’s not really to keep out enemies. It’s just so the King has one more thing
- 00:44
to measure. Of course, Cumference and Meter can’t agree
- 00:50
on how the wall should be built.
- 00:52
Sir Cumference thinks the wall should be circular in design.
- 00:55
Perry Meter envisions a unique polygon shape. Cumference argues that his wall would be more
- 01:01
fun to measure.
- 01:02
<<High-pitched, English voice>> When the King wants to measure the circumference of the
- 01:09
wall, he gets to multiply its diameter by pi.
- 01:16
What is more fun than pi? <<end voice>> But Meter feels that his wall would keep the
- 01:24
King busy longer.
- 01:26
Not to mention that it would be more interesting to look at.
- 01:35
<<Low, English voice>> But a circle is so boring. Two seconds and he’s done.
- 01:43
With my wall, the King can while away an entire afternoon…
- 01:47
…walking around the perimeter and measuring each side, then adding them all together.
- 02:00
<<end voice>> The men kept at each other’s throats for
- 02:21
the remainder of the afternoon.
- 02:23
They never did come to a decision.
- 02:25
However, the King wasn’t upset that his wall wasn’t getting built.
- 02:28
In fact, it had sort of been his plan all along.
- 02:31
<<King voice>> Do you know how long they’ve been arguing in there?
- 02:36
<<Jester voice>> No, sire.
- 02:38
<<King voice>> Four hours, seven minutes, and thirty-two seconds. Isn’t it wonderful?
- 02:42
<<Jester voice>> I suppose, sire…
- 02:44
<<King voice>> Now scram. I’ve got more counting to do. Thirty-seven, thirty-eight…
- 02:49
Blurb: Meet Sir Cumference and Perry Meter. The most
- 02:59
uproarious duo since Martin and Lewis. Or Nichols and May. Or Harold and Kumar. Whatever
- 03:03
reference works for you. They’re here to talk about measuring stuff. Let the hilarity…
- 03:12
ensue.
