Anyway, this is simple to do, especially when they are on the same sheet (I've done it hosting my work's annual Jeopardy! tournament). At the last taping of Jeopardy! I went to, Alex flubbed about 5-10 clues, that were just picked up again in post.
I don't think it's anything to worry about. Typical tabloid stuff.
//Wait, doesn't Alex always read the answers?
