The Irish Times special on the 400th anniversary of Shakespeare's death last Saturday was a celebration devoutly to be wished. However, the hideously inappropriate metaphor employed by Peter Crawley about Shakespeare's contribution to our vernacular ("flowing as usefully as fluoride through the water supply") struck a bum note. Most European countries including Germany, Sweden and Denmark ban fluoride in water because of its health risks. Shakespeare's language enriches and invigorates our discourse without any attendant perils.
