as far as I know...'mr cern' was another programmed 'b/w cat' - just like gill....gill who had probably been to the LONDON SCHOOL come to think of it....

anyway, this is a reference to 'mr cern' hiding from JUDITH i.e. INGA and quasi JOANNE COLLIE.....that would put you off your beer, wouldn't it?

"Judith Slaying Holofernes is a painting by the Italian early Baroque artist Artemisia Gentileschi completed between 1611–12.^[1] The work shows an apocrypha scene from the Old Testament Book of Judith which details the delivery of Israel from the Assyrian general Holofernes. In this scene, Holofernes has been seduced by Judith, who along with her maidservant behead the general after he has fallen asleep drunk."
