that just takes the biscit. A couple of my students didn't even go that far, there's nothing like being able to put two printouts on top of each other and hold them up to the light revealing just one solution :)
Saying that of course one of the guys on my year did take it one step further, by stealing another students assignment, photocopying it, and handing in the photocopy!
complete with the original students name crossed out at the top :-}
