I remember one particular quorte from a book on bar hopping and mongering in Thailand which I often tell when drinking:-
"Sometimes I feel that my only purpose in life is to be an example to others of not how to live theirs"
I am sure someone really famous is behind this - Who is the question?
Another famous quote I like is from the Rangers Corp during the Korean conflict:-
"I see see it all, she loves another. I'll have my revenge I'll f*ck another"
