To SIN, as promised I researched our wise man quote with no definitive results on the author, but the quote itself seems consistent. A google search attributed the quote to Mark Twain, as I had thought, in several of the hits......

Speaking of fools, my pal Mark Twain used to say, "Better to remain quiet and be thought a fool, than to speak and remove all doubt!"

But another (The History Channel)attributed it to Abe Lincoln....

The Best American General....


---------------------------------------
"It is better to remain quiet and be thought a fool than to speak and remove all doubt." Abraham Lincoln

Hundreds of other hits had the exact quote and attributed it to "unknown" or "anonomous".

Whoever first quoted it I'm still not sure, but it is older than your Dad anyway:-)

And a very good quote to live by.....
