I should emphasise that the above is NOT necessarily an exact version of a collected rhyme. It is reeconstructed from the ten words above in the thread, plus "bunkin", which is one of a group of similar words, such as "bumfit" and "bumfrey", according to the rule by which all the versions I have were apparently generated. Thew source I used actually omitted "bunkin" from one of the versions, and I ask the children to find out what the missing word is. Soem of them can do it.
