On the wisdom of marking things down on paper

This was a comment reply discussing a prop on the table of an important Romulan personality (a pro-consul or senator) from Star Trek: TNG's Unification two-parter. The discussion was then about real-life things used in sci-fi as props, and I put the following related memories into that discussion.

I have somewhere the Canadian TV Guide's 1996 "30th Anniversary Star Trek" edition that contains feature articles, production how-tos, and episode guides up to VOY's "Basics", and there was one article, where set design and props people explained, how they'd add funny easter eggs to props that had text on them.

The tv guide was a gift and was supposed to be a collector's item for me, but being a youngish kid and very nearly totally unaware of this, I used pen or pencil (whichever was available) to mark down episodes I'd recently seen as ok/not ok. I wish I'd copied episode titles on separate pieces of paper at least, but back then, this thought never crossed my mind. Poor tv guide collector's edition, I grieve thy former purity :\

Then in the late-1990s/early 2000s I learned of Farscape, and somewhere out on the interwebs there was a website that documented the many bloopers in Farscape, including real-life stuff that was converted into some fantastic sci-fi thingy :-)
