My high school used The Print Shop to make a lot of signage. Having an eye for fonts and a computer and printer at home made it easy to produce fake signs that appeared superficially to be whatever sign I was replacing. "ALL LOCKERS ARE SCHOOL PROPERTY AND MAY BE SEARCHED AT ANY TIME" was easy to change into "ALL THOUGHTS ARE SCHOOL PROPERTY AND MAY BE CONTROLLED AT ANY TIME", etc.
Not having a laminator lowered my success rate at keeping fake signs up, but just putting up new copies worked well until I got caught in the act.
Aside: Anybody remember the Easter Egg game hidden in the Apple II version (and maybe others) of The Print Shop Companion?
