Name of the game: Christmas Switch Game
Object of the game: To have the most creative and/or longest-lasting switch before someone notices and returns item to regular position.
Description: My family plays this game most often at Mom's house, and it's hilarious. Usually it involves all the kids ganging up against Mom; we do the switches so she has to recognize them and change them back. Examples from the past include taking one picture off the wall and switching it with another, flipping pictures upside down, switching a cello with a guitar, swapping an exercise bike with a real bike, taking the towels from the bathroom and interchanging them with towels from the kitchen, and lots lots more.
Genesis: The game began one year when we helped Mom take down Christmas decorations from around the house and put up the usual furnishings. It started with innocent/purposeful crooked picture hangings--just to drive Mom a little nuts--and quickly evolved into the full-fledged switching game of today.
Game Records: Though I could have erroneous information, the longest lasting switch was one that occurred in Midland and lasted for months before Mom noticed it. One year during the Christmas break, a clever someone (I'm thinking Spencer??) swapped the order of kid pictures such that we were no longer in age order. I saw it, laughed for about a week every time I walked down the hall, but then quickly forgot about it. Probably in February or March Mom finally recognized the change. Thinking it was recent, she accused me -- naturally, the only other house resident at the time. After denying all associations with said crime, I recalled the switcharoo Spencer pulled months previously and mentally applauded the big bro.
Strategies commonly employed: Subtlety is the name of the game, folks. Okay, really I just named it the Christmas Switch Game, but you get the idea. Using all of your creative juices and all of your available rooms and props is key. Items with similar characteristics are often the best swapped. Don't overdo it in one room because though it is still funny, the changes will all be noticed right away. More humor results when you tastefully spread out your attack and the new features are noticed over time. Especially good switches are met with laughter, confusion, or embarrassment (in the case of switch-recognition during or following the presence of guests in the home).
Most recent attack: Yesterday. Mom and I were out of the house all day, and the siblings (for anonymity purposes, we'll code-name them Jennifer, Emily, and Jon) came over to celebrate a birthday with our food and to use the HDTV to watch a CES fireside. I returned home late at night to discover that quite a few things had swapped places in my absence. Luckily for the culprits, I laughed so much I'm even leaving the items swapped so that Mom can likewise discover them when she returns home in the next 24 hours.
Future game plans: The aforementioned leftovers for Mom. But as for creative/new attacks . . . well that's for you to decide, isn't it?
