The Ripper:

Jack be nimble,
Jack be quick,
Jack jump over the candlestick.

Jack be crazy,
Jack be sick,
Ripper's become the Reaper's pick.

Jack hath bloodlust,
Jack hath skill,
Two natural things needed to kill.

Blood on his mind,
Oh so thirsty,
Clean though his blade, his hands be dirty.

Jack be silent,
Jack be slick,
You'll never feel the blade so quick.

Jack's just started,
Jack's not done,
Stalk, rape, kill, doesn't that sound fun?

Jack be nimble,
Jack be quick,
Jack belongs as the candle's wick.
