Various memory-related games involve reciting a list of items; each time you recite the list, you add a new item to it. The act of reciting the full list each time makes it much easier to remember the entire list as it grows.
Some years back, Ed Cook taught us a list of eleven items to memorize. I wasn't paying full attention, so never learned it, but others who were there learned it so well they could still recite most of it years later. The list started with "one duck" and then "two squawking geese"; each additional item grew longer and sillier, employing rhyme, consonance, assonance, alliteration, and other forms of echoing sounds. The ninth item on the list, for instance, was "nine apathetic, diabetic, diuretic old men on roller skates with a marked proclivity for procrastination and sloth."
We later learned that this list derived from a novelty song of some sort, written in the '50s or '60s, called something like "The Indian Memory Trick." Ed and Jim Moskowitz were so taken with the list that they came up with some additional items, and then took turns coming up with items for a new similar list. If you feel the urge to try to memorize it, speak the first item aloud (preferably in chorus with a group of other people), then the first two in order, then the first three, and so on. Alternatively, come up with your own list!
