Douglas Noel Adams (aka "DNA") is perhaps the one Earthling known to a wide section of the galaxy's intelligentsia,
primarily for the shear chutzpah of suggesting that one can "see the galaxy for less than 30 Altarian dollars a day"
through the advanced (and highly questionable) hitchhiking techniques offered by the (perhaps) fictional book "The
Hitchhiker's Guide to the Galaxy."
Besides the beloved "Hitchhiker's Guide to the Galaxy" (a massively friendly and utterly dangerous book, in that
many of its articles are "inaccurate, or at least highly apocryphal"), he is also the Creator of Dirk Gently
(of Dirk Gently's Holistic Detective Agency -- a sort of "quantum private investigator"), much humor for the
Monty Python crowd, and was also a fan of repairing the Earth's ecosystems.
[MIB footnote: there is no evidence to support the claim that the Draconians had him
"eliminated" in order to suppress "the galaxy's most famous Earthling's" efforts to restore the planet's original
ecology.]
"More importantly, a towel has immense psychological value. For some reason, if a strag (strag: non-hitch hiker) discovers that a hitch hiker has his towel with him, he will automatically assume that he is also in possession of a toothbrush, face flannel, soap, tin of biscuits, flask, compass, map, ball of string, gnat spray, wet weather gear, space suit etc., etc. Furthermore, the strag will then happily lend the hitch hiker any of these or a dozen other items that the hitch hiker might accidentally have "lost". What the strag will think is that any man who can hitch the length and breadth of the galaxy, rough it, slum it, struggle against terrible odds, win through, and still knows where his towel is is clearly a man to be reckoned with."
