It happens to me every time I pick up a quick lunch from a fast-burger franchise. I think "hey, this reminds me of Monolith Burger....hee hee hee". Then when I go back to my cubicle, I think, "hey, this reminds me of the cubicle maze on Pestulon, but that one had people walking around cracking whips". Then when I go home and watch some show that has killer robots, I think, "hey, this reminds me of being hunted by Arnoid".
And at that point I'm quite grateful that in my everyday life making one little mistake won't result in bloody death or encasement in lime gelatin.
