Philosophy's "On a Clear Day" face wash. Technically, they changed the formula and kept the name but now I'LL NEVER BE PRETTY AGAIN so I think it counts.
9th grade French -- I had a cheat sheet of verb conjugations hidden in my desk and my teacher busted me cold -- I was horrified -- my brother (love that guy) ratted me out to my parents.
In 7th grade, our nun (Sister Charles Manson, if I remember correctly) caught one of my classmates, Steve, copying test answers from one of the smart girls sitting next to him. The nun called Steve up to the front of the classroom, grabbed him and spun him into the blackboard. As he hit the board backwards, the blackboard came loose at the top and fell onto Steve’s back. He staggered under it to prevent it from falling to the floor. A couple of the male students in the front row jumped up to grab the blackboard off Steve’s back and lower it to the floor. That incident was the buzz for the rest of the school year.
In 3rd grade, I had a spelling test and couldn't remember how to spell spaghetti so I wrote a note and taped it inside my desk. I felt so guilty about the prospect of cheating that I figured out a better way to remember the spelling and removed the note before the test.
I wrote the first 3 pages of a 10 page paper, stapled 4 pages together (the 4th being blank), then tore of the 4th page at the corner and handed it in. I got an A+ and an apology for losing the last 7 pages. Must've happened while she was transferring it from her desk to her bag after grading it.
In high school, there was a guy who treated cheating on tests as an art form. Among his techniques: printing a cheat sheet in 7-point font and putting it down his pants so he could unzip his fly, bend over to tie his shoe, and look at the sheet. Also, he sometimes covered bottles of Wite-Out with Wite-Out and wrote information in tiny letters on the outside of the bottles, leading to the following exchange during a test: "Hey, can I borrow your Wite-Out? No, not that one--the other one."
