34 out of 40 for me, too.
Why is a picture of Press Your Luck Expert Edition (I think that's what it is) used for the first question? And even then it looks pixely, like someone screencapped a YouTube video at 240p resolution or somesuch.
The Ray Combs question has nothing even resembling the right answer - the "correct answer" only happened to him after his last Family Feud taping and dismissal.
Gotta love the questions where the picture gives away the answer. At least make me think a little!
It's a shame, though, since like Matt said this does have some good questions...but the factual errors and some bad picture choices drag it down for me.
