Here's Death and Taxes's collection of 18 obsolete words that would be handy (or at least funny) to use today, compiled by Carmel Lobello from a book called The Word Museum and a blog called Obsolete Word of the Day. Some of my favorites:
Snoutfair: A person with a handsome countenance — "The Word Museum: The Most Remarkable English Words Ever Forgotten" by Jeffrey Kacirk
Groak: To silently watch someone while they are eating, hoping to be invited to join them – www.ObsoleteWord.Blogspot.com
Spermologer: A picker-up of trivia, of current news, a gossip monger, what we would today call a columnist — "The Word Museum: The Most Remarkable English Words Ever Forgotten" by Jeffrey Kacirk
Jirble: To pour out (a liquid) with an unsteady hand: as, he jirbles out a dram — www.Wordnik.com
