In the early 1980s, when people had just begun to hear about laser printers and they were huge and expensive, I fooled my classmates into thinking I owned one by Xeroxing some images from a magazine onto pin-fed printer paper.
Never mind that laser printers don't use pin-fed paper: the fact that it was obviously printer paper of some sort, and yet contained a high-resolution image that was evidently produced by something laser-like, blew my friends' minds.
