So long, Douglas, and thanks for all the wit

Today is Towel Day. The commemoration day for the late Douglas Adams who authored The Hitchhiker’s Guide to the Galaxy. So carry your towel the whole day with you, wherever you go.
After all, "a towel is about the most massively useful thing an inerstellar hitchhiker can have. Partly it has great practical value. You can wrap it around you for warmth as you bound across the cold moons of Jaglan Beta; you can lie on it on the brilliant marble-sanded beaches of Santraginus V, inhaling the heady sea vapors; you can sleep under it beneath the stars which shine so redly on the desert world of Kakrafoon; use it to sail a miniraft down the slow heavy River Moth; wet it for use in hand-to-hand-combat; wrap it round your head to ward off noxious fumes or avoid the gaze of the Ravenous Bugblatter Beast of Traal (such a mind-boggingly stupid animal, it assumes that if you can't see it, it can't see you); you can wave your towel in emergencies as a distress signal, and of course dry yourself off with it if it still seems to be clean enough."
Alternatively, make a list of everybody you know and then insult them methodically. Insult me and give it your best and your worst. Recite your Vogon poetry. Hitchhike wearing a bathrobe and a towel.
Whatever you do, record it and send it in.
