It's obvious, Stu.
In this cipher, you can take any letter in any word and substitute it with any other letter or punctuation mark.
So,
S => C => S => M => W
H => O => A => O => A
I => D => L => T => L
P => => T => H => L
S => A => & => E => S
I => N => V => R => H
M => D => I => - => A
U => => N => I => V
L => C => E => N => E
A => H => G => - => E
T => I => A => L => A
O => P => R => A => R
R => S => ! => W => S
Easy when you know how...
This of course proves conclusively that the ancient Egyptians could foretell the prophesies of Nostril d'Armus. The venusians obviously helped them with this.
Or something...
Can you tell that I'm not taking any of this terribly seriously?
