When I was younger, I worked a summer at a small engine repair shop (really fun job, btw). Between the shop and the parts room, there was a small corridor with doors on either end. We called it the "Hall of Dumb", because as soon as you walked through there, you'd inevitably forget what you were going to get.

This is why all the rooms of my Memory Palace are connected by windows. Or slides.
