It is not really a "tip," but I thought it interesting nevertheless:
In a banquet speech that must have been at least ten years ago, I made the following comment (which is fiction, by the way):
"After Smithton County had their county marriage records digitized, the county board contemplated what to do with the originals. In an effort to conserve space, save money, and express concern for the environment, they decided to submit them to the local paper recycling center. Board President Wannabee Paula Tician commented 'this allows us to reduce county expenses and even lets dead people help with recycling.' The next time you get to 'choose' between 'paper' and 'plastic,' your great-grandparents' marriage license might literally be 'in the bag.'"
