Thats Not A Hat game

You're constantly giving each other gifts and trying to remember who has what gift in front of them at any given moment. 
Does memorizing 2 objects seem easy?    Yet barely memorized you have already forgotten it…and here you are with a bulky gift on your hands. 
If you are not sure of the object in front of you, it is up to you to bluff convincingly enough to pass the unknown object on to another player.    The latter can either believe you and accept your gift, or refuse it by saying that you are lying... at the risk of making a mistake and getting a negative point!A memory game... or at least where you have to pretend to have one. 
Simple, surprising and... simply unforgettable.
