It was one of the local councils in Scotland ( Flintshire, I believe) that decided to change the name spotted dick to spotted richard because of of the staff that used the canteen kept making 'childish and immature comments' that annoyed one of the canteen staff. However they received so much bad publicity for doing so that they have now agreed to change the name back to spotted dick.
to quote them, ' ...if we offend any spotted Dicks in the process then tough, they can eat jam rolly poly instead'

three cheers for that!!
