drawn and quatered by donkeys?
I don't know. I'm sure someone will think of something.
On second thought. why death ??? I remember some show in the 70's where everytime a guy woke up he was missing a limb, until he was just a body with a head ...That sounds like a good punishment to me !! Stuck in a bed without any hope of mobility till he too need a feeding tube and then the legal system can starve him to death .
