I remember today's one from late last year. Or should I say I remember Katie.

After two questions in the jackpot round the jackpot counter was nearly over. I'd have made her a big favourite to win it, were it not for the fact I remembered that she didn't.
She started going for two point questions half way through the round, presumably as a sort of hedge, because she felt it was better to make sure she got some counters rather than try for three pointers and get them wrong. In the end it didn't work. Of the three two pointers she took, she got only one of them right and her game fizzled out.
As has been said here before, if you're weak on a subject, you might as well go for a three pointer anyway. If you don't know much about a subject, there's a good chance you'll end up having to guess on the two pointer as well.
I was pleased that in the "Let's see if you would have won" bit, she wouldn't have won it. Even though that bit is completely meaningless.
