I Googled Plod.... The first one it talks about Donkeys plodding...kind of thought you were calling me a Jacka$$ for a second...
http://www.answers.com/topic/plod
went to the next link they had...."Plod or P.C.Plod is a British slang term used to refer to a a police officer, particularly one slow-witted or dull, or - more recently - the police force in general.....""
http://en.wikipedia.org/wiki/Plod
Not sure which one is better...to be called a Jacka$$ or a slow-witted and dull police officer.
Either way...good morning Chris!!!
