"I thought I put my keys in the bowl next to the front door"...spends 15 minutes looking for keys only to find them in your hand.
Memory is unreliable, especially with things that happened long ago, or that you didn't pay particular attention to. There are a few examples of the ME that I personally never got mixed up, but it was because I was exposed to those things a lot and I payed attention to them often. Most of the shit people are confusing are brand names or entertainment titles being different. Now if I woke up tomorrow and the twin towers were standing in New York, I would start to become suspicious of some ME fuckery.
