I used to work for the Better Business Bureau, and we’d see stuff like this sent in as “is this for real?”

There was one that looked like a page ripped out of a magazine, with margin notes in pen, highlighter and a sticky note, folded up, and placed in a non-descript envelope. It was supposed to look like a friend had helpfully sent it to your attention. But the folds were too crisp, and when you folded it up, the rips lined up, so it was clear the complete pre-folded page had been ripped off a pad of pre-folded pages, complete with pre-printed “pen” notes and highlights, and all it needed was a pre-printed “handwritten” post-it attached (initialled “L.” or “J.”) before being stuck in the envelope…

My phonebook does the same. There’s a Domino’s yellow page ad that includes a handwritten “Best Place!” with a circle around it, made to look as if someone had scribbled it helpfully in my phone book… The bastards! Who’s vandalizing my pristine phone book! I demand to know!
