For people over a certain age their strongest memory of Mark Twain might be Hal Holbrook's brilliant impersonation in Mark Twain Tonight. Younger products of our public education system may remember him as that writer whose use of the "N" word got his books banned from their school libraries.
Anyway, today is his birthday. He was born November 30, 1835, in Florida, Missouri. (Via Britannica.com.)
Happy Birthday, young man!
