I spotted Professor Will's Millenium punch script.
Caz Frost wrote this interesting article on Punch and Judy from a feminist perspectve. In her version punch has to watch the baby because it's her turn to go to the pub, and after he makes the baby into sausages, she promises to use the insurance money for a vacation for herself.
Other writers question whether political correctness will have any real impact on the nature of Punch and Judy shows which are little different than the victorian ones. Probably this is because one person does the whole show and the puppets are obviously extentions of the Professor.
