Missing Tile Syndrome: if a ceiling is missing one tile, that's all you notice about the ceiling.
 

My counter to his theory is this:  You only focus on the missing tile(s) if they happen to be fewer than the tiles that are there.  If you had an entire ceiling with only ONE tile in place, you would probably focus more on that one tile since it stands out.
 
I arrive at this conclusion after having lost most of my tiles (and a similar amount of my marbles).

This applies to GAS much more literally if you have a modular! 

What about when your bathroom floor tile pattern resembles a panda? That's all I notice when I'm on the can. Cannot unsee.

Aren't you supposed to bear it in the bathroom? 

Hi,
 
Bit ... we need to revisit  one of the original (???) bits by Yoko ... remember that she had a white wall in a big show, and the only thing in it was a ... black dot on it. 
 
And, of course, all you noticed, was the black dot! And John Lennon loved it! The point was found!
