I failed utterly. I did notice there was a large funny shaped player blocking my view at points, and was annoyed because it was making it harder to count the passes - but I didn't notice it was a gorilla. I also missed the moonwalking bear in the second one - even though I knew something would be there.
Got the number of passes right on both vids and saw the gorilla, but didn't see the bear although I saw it mentioned in the commnents before watching it. In my defence it was hardly a bear and hardly moonwalking.
