"‘Tis better to remain silent and be thought a fool, than open one’s mouth and remove all doubt." - anonymous You might not believe it but this the phrase I coined years ago. . .I am not sure where I used it first. Then again. . I might have opend my "mouth" here a bit too soon! :-) PS: On Internet it is claimed the citation comes from a guy called Samuel Johnson. It is obviously a blatant lie if I said it first!
