Caption: The official portrait of Mark Twain (1835--1910) as doctor of letters, (honoris causa, Oxford University, 1907) in academic dress (see Wikipedia: Mark Twain: Later life and death).

What good's an alias if everyone knows you are really old Sam Clemens?

Yours truly's favorite misquote from Mark Twain:

There is nothing so phony as an untested virtue.
---Mark Twain (1835--1910), misquoted from Directory of Mark Twain's maxims, etc.: Virtue

Another goody: On being told he was NOT getting the Nobel Prize in Literature:

It's better to deserve these things and not get them than the other way around.
---Mark Twain (1835--1910), misquoted from memory.
