Don't wanna be a spoilsport but yes, I saw it.
We did the test in one of our classes of Perceptional Pychology and the prof asked whether "Anyone saw something out of the regular".

I, on the other hand, couldn't believe how you could miss it
But since most people don't, I'm probably the one who is a bit weird
