Not quite off-topic, Any Terry Pratchett (Discworld) fans out there ?
The following was based on one of the recurring characters, and tuned to "Old Dope Peddler"
Cut-Me-Own-Throat Dibbler
Nigel Parsons 1998
When 'The Shades' at night are crawling,
Comes a fellow everyone knows,
Cut-Me-Own-Throat Dibbler,
Slicing meat from corpses toes.
Ev'ry afternoon you'll find him
In the market's neighbouhood,
Cut-Me-Own-Throat Dibbler,
Doing harm by selling food.
He gives the kids free samples,
Because he knows full well;
Though they've seen his meat suppliers,
When they're dead, They'll never tell.
Though 'The Watch' are quite unable,
To tell how many he has killed,
Dibbler heads the merit table
Of Ankh-Morpork's Assassins Guild.
