Kai, don't make yourself look special in front of the camera.

But being serious, the fourth wall has been broken 3 times (so far):

Lloyd saying "Is it Wednesday already?" in season 2 is the first.

Griffin Turner looking at the camera and asking the audience "How many buttons does that man HAVE?" is the second.

And Nadakhan saying "ghosts are SO last year", when POSSESSION aired is the third.
