and didn't get his butt kicked.
he's a freshman and was taking a biology exam. He just started the test when he saw that the guy next to him was trying to copy. So, ds very calmly puts down all the wrong answers on the test, letting neighbor copy, takes the test up to his teacher, doesn't hand it in, waits until the other kid hands back his test, then sits back down and puts all the right answers in.He told his teacher after wards and she even laughed.
That's my boy!!!
I did exactly the same thing in senior English, except I told the teacher what was going to happen ahead of time. "Joe" was a charmer who cheated nonstop. I hated cheaters. Joe assumed I'd let him cheat off me on a major test and he needed a good grade in the worst way, as he was close to failing senior English. And if he failed that, he might not graduate. I told him no, but he just kept insisting and took it for granted that I'd go along. Eventually, I said, "Sure, you can. I'll make certain I write really BIG."
I told the teacher what he was going to do. I wrote all the wrong answers (ABCD) in HUGE letters and he gleefully copied, telling me afterward how smart he had been to change a few, so the cheating would not be obvious.
Those were the only ones he got right. He paid no attention when I erased every single answer and wrote in the correct answer after he had turned in his test . I made a 100 and he made something in the teens. 
He was stunned and never guessed what I had done. I looked at him with a straight face and said, "I'll bet I know what happened. I'll bet she gave us different versions of the test."
A light went on in his head and he was devastated to have been thwarted in his attempt at a certain A. He called the teacher a nasty name and had to work his butt off to not fail senior English. 
I loved it.
