Prince Charles and his wife Camilla observed the process for a commemorative Queen’s Diamond Jubilee cheddar cheese at the Dairy Crest creamery Tuesday.    There was an awkward moment when a dairy employee mistook Camilla for a cow and tried to milk her.

Being a good sport, Camilla gave about 2 gallons.
